This document is intended for the use of individuals who are competent to evaluate the sig-nificance and limitations of its content and recommendations and who will accept re-sponsibility for the application of the material it contains. The American Concrete Institute disclaims any and all responsibility for the stated principles. The Institute shall not be liable for any loss or damage arising therefrom.Reference to this document shall not be made in contract documents. If items found in this document are desired by the Architect/Engineer to be a part of the contract documents,they shall be restated in mandatory language for incorporation by the Architect/Engineer.Cement and Concrete TerminologyACI 116R-00FOREWORDThis report is the authoritative glossary for cement and concrete technology. It is to be used generally and specifically in ACI tech-nical communications, correspondence, and publications. One mission of Committee 116 is to produce and maintain a list of terms with their meaning in the field of cement and concrete technology.Committee 116 has tried to produce a glossary that will be useful, comprehensive, and up-to-date. It recognizes, however, that the listing may not be complete and that some definitions may be at variance with some commonly accepted meanings.Users of the glossary are invited to submit suggestions for changes and additions to ACI Headquarters for consideration by Com-mittee 116 when preparing future editions. In the event that a user disagrees with any of the definitions, it is hoped that the reasons for such will be given to the committee.The committee is aware that some of the definitions included may seem entirely self-evident to an expert in the concrete field. This occurs because no term has been discarded if there was reason to believe it would appear to be technical in nature to a casual reader of the ACI literature.The committee voted to use the following procedural rules:1. Each definition shall be stated in one sentence;2. Each definition shall consist of the term printed in boldface, a dash, and the definition statement;3. The definition statement shall not repeat the term and should state the class or group and identify the features unique to the term;as “mathematics —the science of numbers and spaces”;4. Verbs should be stated in the infinitive rather than the participle; for example the term to be defined should be “abrade ” not “abrading”;5. Notes may be appended to definition statements;6. Cross references may take the place of a definition as “green concrete —see concrete, green .” They also may call attention to related items as “flint —a variety of chert. (See also chert ).” Where the committee has found two or more terms with the same meaning,the definition is given where the preferred term appears, the synonyms are cross referenced to the preferred term, and in many cases,the fact is stated;7. Generally, where there are a number of terms, the last word of which is the same, the definitions are given where the terms are listed in the inverted form, as “cement, low-heat ” rather than “low-heat cement ,” but under the latter entry, there will be a cross ref-erence “see cement, low-heat ;” and8. In selecting terms and definitions, there shall be coordination with the terminology subcommittees of ASTM Committees C-1on Cement, and C-9 on Concrete and Concrete Aggregates.The invaluable contributions of the past chairmen of Committee 116, B. J. Erlin, R. C. Mielenz, D. L. Bloem, W. H. Price, R. E.Davis, Jr., J. R. Dise, K. F. Gibbe, Robert L. Henry, M. D. Luther, B. Mather, and E. Senbetta, those of the present members of the committee, as well as the diligent efforts of William Lorman and Lewis H. Tuthill, are gratefully acknowledged.For drafting this edition, all members, both associates and voting, participated.Reported by ACI Committee 116Glen Bollin Richard H. Howe Joaquin Marin Bernard J.

Tolerances are a means to establish permissible variation in dimension and location, giving both the designer and the contractor limits within which the work is to be performed. They are the means by which the designer conveys to the contractor the performance expectations upon which the design is based or that the project requires. Such specified tolerances should reflect design assumptions and project needs, being neither overly restrictive nor lenient. Necessity rather than desirability should be the basis of selecting tolerances.As the title “Specifications for Tolerances for Concrete Construction and Materials (ACI 117)” implies, the tolerances given are standard or usual tolerances that apply to various types and uses of concrete construction. They are based on normal needs and common construction techniques and practices. Specified tolerances at variance with the standard values can cause both increases and decreases in the cost of construction.The required degree of accuracy of construction depends on the interrelationship of many factors:Structural strength and function requirements—It is imperative that structures satisfy the basic code requirement to protect life safety and are constructed in conformance with the contract documents.Aesthetics —The structure should satisfy the aesthetic requirements of the contract documents.Economic feasibility —The specified degree of accuracy has a direct impact on the cost of production and the construction method. In general, the higher degree of construction accuracy required, the higher the construction cost.R elationship of all components —The required degree of accuracy of individual parts can be influenced by adjacent units and materials, joint and connection details, and the possibility of the accumulation of tolerances in critical dimensions.Construction techniques —The feasibility of a tolerance depends on available craftsmanship, technology, and materials.--`,,```,,,,````-`-`,,`,,`,`,,`---117-4ACI STANDARD/COMMENTARYSTANDARD COMMENTARYCompatibility—Designers are cautioned to use finish andarchitectural details that are compatible with the type andanticipated method of construction. The finish and architec-tural details used should be compatible with achievableconcrete tolerances.Job conditions—Unique job situations and conditionsshould be considered. The designer should specify andclearly identify those items that require either closer ormore lenient tolerances as the needs of the project dictate.Measurement—Tolerances should be evaluated usingcontrol points and benchmarks that have been planned,established, and coordinated prior to execution of the work.Control points and benchmarks should be maintained in anundisturbed condition until final completion and acceptanceof the project.Project document referencesACI specification documents—The following AmericanConcrete Institute standards provide mandatory requirementsfor concrete construction and can be referenced in theProject Documents:117Specifications for Tolerances for Concrete Construction and Materials and Commentary 301Specifications for Structural Concrete301M Specifications for Structural Concrete (metric) 303.1Standard Specification for Cast-in-Place Architectural Concrete306.1Standard Specification for Cold Weather Concreting308.1Standard Specification for Curing Concrete 330.1Specification for Unreinforced Concrete Parking Lots336.1Specification for the Construction of Drilled Piers346Specification for Cast-in-Place Concrete Pipe 423.6Specification for Unbonded Single-Strand Tendons and Commentary503.1Standard Specification for Bonding Hardened Concrete, Steel, Wood, Brick, and OtherMaterials to Hardened Concrete with a Multi-Component Epoxy Adhesive503.2Standard Specification for Bonding Plastic Concrete to Hardened Concrete with a Multi-Component Epoxy Adhesive503.3Standard Specification for Producing a Skid-Resistant Surface on Concrete by the Use of aMulti-Component Epoxy System503.4Standard Specification for Repairing Concrete with Epoxy Mortars506.2Specification for Shotcrete530.1Specification for Masonry Structures and Commentary --` , , ` ` ` , , , , ` ` ` ` -` -` , , ` , , ` , ` , , ` ---TOLERANCES FOR CONCRETE CONSTRUCTION117-5 STANDARD COMMENTARY548.4Standard Specification for Latex-ModifiedConcrete (LMC) OverlaysACI informative documents—The documents of thefollowing American Concrete Institute committees coverpractice, procedures, and state-of-the-art guidance for thecategories of construction as listed:General building...................ACI 302, 304, 305, 311, 315Special structures......ACI 307, 313, 325, 332, 334, 343, 358Materials.......................................................ACI 211, 223 --`,,```,,,,````-`-`,,`,,`,`,,`---117-6ACI STANDARD/COMMENTARYNotes --`,,```,,,,````-`-`,,`,,`,`,,`---STANDARDCOMMENTARYTOLERANCES FOR CONCRETE CONSTRUCTION 117-71.1—Scope1.1.1 This specification designates standard tolerances for concrete construction.1.1.2 The indicated tolerances govern unless other-wise specified. Tolerance values affect construction cost. Specific use of a tolerance item may warrant less or more stringent tolerances than contained in the specification. Such variances must be individually designated by the specifier in the contract documents.Tolerances in this specification are for standard concrete construction and standard construction procedures. Materials that interface with or connect to concrete elements may have tolerance requirements that are not compatible with those contained in this document.This standard is not intended to apply to special struc-tures not cited in the standard, such as nuclear reactors and containment vessels, bins, prestressed circular structures, and single-family residential construction. It is also not intended to apply to precast concrete or to the specialized construction procedure of shotcrete.Specialized concrete construction or construction procedures require the specifier to include specialized tolerances. AC I committee documents covering specialized construction may provide guidance on specialized tolerances.1.1.3 A preconstruction meeting shall be held. All parties shall be given the opportunity to identify any anticipated tolerance questions that are applicable to their work. These questions shall be resolved before the beginning of applicable construction.1.1.4 Hard conversions were used throughout the document. Use the tolerances specified in inch-pound units if the structure was designed using inch-pound units, and use the tolerances specified in SI units if the structure was designed using S I units. I t is not permitted to convert from one system of units to another to obtain larger tolerances.1.1.5 Values stated in either inch-pound or SI units shall be regarded separately as standard. Values stated in each system might not be exact equivalents;therefore, each system must be used independently from the other, without combining values in any way.SECTION 1—GENERAL REQUIREMENTS--`,,```,,,,````-`-`,,`,,`,`,,`---117-8 ACI STANDARD/COMMENTARYSTANDARD COMMENTARY1.2—Requirements R1.2—RequirementsAn example of a specific application that uses a multiple oftoleranced items that together yield a toleranced result is the location of the face of a concrete wall. The wall has a tolerance on location (Section 4.2.1), measured at the foundation of the wall, and is allowed to deviate from the specified plane (Sections 4.1 and 4.8.2). The application of the location tolerance (Section 4.2.1) cannot be used to increase the plumb tolerance contained in Section 4.1. Similarly, the tolerance on member thickness (Section 4.5) shall not be allowed to increase the tolerance envelope resulting from the application of Sections 4.1, 4.2.1, and 4.8.2. If the base of the wall is incorrectly located by the maximum amount allowed by Section 4.2.1, then the plumb tolerance (Section 4.1) dictates that the face of the wall move back toward the correct location, and at a rate that does not exceed the provisions of Section 4.8.2. Refer toFig. R1.2.3.Fig. R1.2.3—Use of multiple of toleranced items to yield toleranced result.1.2.1 Concrete construction shall comply with specified tolerances.1.2.2 T olerances shall not extend the structure beyond legal boundaries. T olerances are measured from the points, lines, and surfaces defined in the contract documents. I f application of tolerances causes the extension of the structure beyond legal boundaries, the tolerance must be reduced.R1.2.2 If the application of tolerances causes the extension of the structure beyond legal boundaries, consideration should be given to reduce the specified dimension to accommodate the tolerances.--`,,```,,,,````-`-`,,`,,`,`,,`---TOLERANCES FOR CONCRETE CONSTRUCTION 117-9STANDARDCOMMENTARY1.2.3 Tolerances are not cumulative. The most restric-tive tolerance controls.R1.2.3 Accumulations of individual tolerances on a singleitem should not be used to increase an established tolerance.Individual tolerances are unique to their specific application and should not be combined with other tolerances to form a tolerance envelope. The separately specified tolerances must remain separate and not cumulative. Each tolerance stands alone when evaluating the acceptability of concrete construction. Refer to Fig. R1.2.3.1.2.4 Plus (+) tolerance increases the amount or dimen-sion to which it applies, or raises a deviation from level.Minus (–) tolerance decreases the amount or dimension to which it applies, or lowers a deviation from level.Where only one signed tolerance is specified (+ or –),there is no limit in the opposing direction.1.2.5 I f the tolerances for structural concrete in this document are exceeded, refer to ACI 301 for acceptance criteria. For other concrete, the engineer-architect may accept the element if it meets one of the following criteria:a. Exceeding the tolerances does not affect the structural integrity, legal boundaries, or archi-tectural requirements of the element.b. The element or total erected assembly can be modified to meet all structural and architec-tural requirements.1.3—Definitionsarris —the line formed by the intersection of two planar or curved surfaces.bowing —the deviation of the edge or surface of a planar element from a line passing through any two corners of the element.R1.2.5 For acceptance criteria for structural concrete, refer to ACI 301, Section 1.7.R1.3—Definitionsarris —refer to Fig. R1.3.1.Fig. R1.3.1—Arris.Fig. R1.3.2—Bowing.bowing —refer t o Fig. R1.3.2.--`,,```,,,,````-`-`,,`,,`,`,,`---117-10ACI STANDARD/COMMENTARYSTANDARDCOMMENTARYbundled bar equivalent area —single bar area derived from the equivalent total area of reinforcing bars contained in the bundle.clear distance —gap between prescribed elements.contract documents —the project contract(s), the project drawings, and the project specifications.cover —in reinforced concrete, the least distance between the surface of the reinforcement and the nearest surface of the concrete.deviation —departure from an established point, line,or plane.

Deviation from plane, in addition to designating allowable relative displace-ments of elements, is used to determine the rate of change of adjacent points (slope tolerance) occurring within the tolerance envelope. In this fashion, the slope and smoothness of surfaces and lines within a tolerance envelope are controlled. Abrupt changes such as offsets, saw-toothing,and sloping of lines and surfaces properly located within a tolerance envelope may be objectionable when exposed to view. The acceptable relative alignment of points on a surface or line is determined by using a slope tolerance.Effective use of a slope tolerance requires that the specifier establish the specific distance over which the slope is to be measured, and that the surface between measurement points does not influence the measurement device.Fig. R1.3.8—Vertical deviation.--`,,```,,,,````-`-`,,`,,`,`,,`---STANDARDCOMMENTARYflatness —the degree to which a surface approximates a plane.levelness —the degree to which a line or surface is horizontal.flatness —refer to Fig. R1.3.9.levelness —refer to Fig. R1.3.9.Fig. R1.3.9—Flatness and levelness.project specifications —the specifications of a specific project that employ AC I 117 by reference.Project specifications are the instrument for making the mandatory and optional selections available under ACI 117 applicable and for specifying items not covered in ACI 117.specified point, line, plane, surface, or dimension —a point, line, plane, surface, or dimension specified by the contract documents.

上混凝土 A 的强度显著高于混凝土 B, 但在工程尺度 上 则可能出现混凝土 B 的强度高于 混凝土 A 的情 况, 如图中 ( b) 所示, 这显然是大家非常担心的情况, 甚至 ( c) 的情况也不是人们所希望的。因此, 混凝土高强化 不能仅仅是在实验室尺度上的强度提高 2 211 混凝土强度尺寸效应的试验研究 抗压强度尺寸效应 Neville

抗拉强度尺寸效应 Malhotra
[10]
采用 ª 10cm @ 20cm 和 ª 15cm @ 30cm 两
种圆柱体试件测定 抗拉强度, 试验结果表明 ª10cm @ 20cm 圆柱 体试件 的抗拉 强度 约比 ª15cm @ 30cm 试 件 的抗拉强度高 7% 。 水科院 的试验结果表 明 [6 ], ª 15cm 圆断 面试件 的 抗 拉 强度 约 比 断 面 15cm @ 15cm 试 件 的 抗 拉 强 度 高 5% , 断面 10cm @ 10cm 试件的抗拉强度约比断面 15 @ 15cm 试件的抗拉强度高 15% 。 Carpinteri [11~ 13] 通过自行研制的试 验仪器, 成功 地 解决了直接拉伸试验中可能存在的弯曲应力问题 , 获 得了稳定完整的拉伸曲线。试验结果表明拉伸强度 具 有显著的尺寸效应, 截面宽度 5cm 的试件强度为 4. 33 MPa, 而当尺寸增大到 40cm 时强度仅为 3. 17MPa 。 对于劈裂抗拉强度, 试验结果表明不论是圆柱 体 试件还是立方体试件它都随试件尺寸增大而减小。 奥 西泽 的研 究显 示, 圆柱 体试 件混 凝土 受拉 断面 大 于 800cm 2~ 900cm2( 直径 d \30cm) 时, 尺寸效应已消失 , 劈裂抗拉强度 趋于稳定而不受试件尺寸 的影响 。 姜 福田则在统计众多试验结果的基础上得出不同尺寸 立 方体试件与 15cm 立方体试件的换算系数, 10cm、20cm 立方体试件换算系数分别为 0. 85、 1. 15 [6]。 3 混凝土强度尺寸效应的理论研究 通过试验获得混凝土强度尺寸效应的结果非常 直 接, 但受到很多限制, 因此很多研究者在如何准确给出 强度尺寸效应公式方面进行了大量的研究工作。 31 1 Weibull 统计理论 自从 1939 年 Weibull 采 用最弱键概 念分析和描 述 强度尺寸效应现象, 并提出著名 Weibull 分布以来, 统 计强度理论已发展为一门引人注目的学科。根 据 Weibull 理论, 对于加载形式相同, 体积为 V 1、 V 2 试件的 平均强度比值可由下式给出。

Standard Specifications for Tolerances for Concrete Construction and Materials (ACI 117-90) Reported by ACI Committee 117S. Allen Face, III Thomas C. Heist Richard A. Kaden Ross Martin Peter Meza W. Robert LittleChairmanRussell S. FlingChairman, Editorial SubcommitteeAndrawos Morcos B. J. PointerClark B. Morgan, Jr.Dean E. Stephan, Jr.*Harry M. Palmbaum Eldon TippingWilliam S. Phelan Carl S. TogniJoe V. Williams, Jr.This specification provides standard tolerances for concrete con-struction. This document is intended to be used as the reference doc-ument for establishing tolerances for concrete construction by speci-fication writers and ACI committees writing Standards.Keywords: bending (reinforcing steels); building codes; concrete construction; concrete piles; concretes; floors; formwork (construction); masonry; mass con-crete; piers; precast concrete; prestressed concrete; reinforcing steels; specifi-cations; splicing; standards; tolerances (mechanics).FOREWORDF1. This foreword is included for explanatory pur-poses only; it is not a part of Standard Specification 117.F2. Standard Specification 117 is a Reference Stan-dard which the Architect/Engineer may cite in the Project Specifications for any construction project, to-gether with supplementary requirements for the spe-cific project.This standard is not intended to apply to special structures not cited in the standard such as nuclear re-actors and containment vessels, bins and silos, and pre-stressed circular structures. It is also not intended to apply to the specialized construction procedure of shotcrete.F3. Standard Specification 117 addresses each of the Three-Part Section Format of the Construction Speci-fications Institute, organized by structural elements, structural components and types of structures; the numbering system reflects this organization. The lan-guage is imperative and terse to preclude an alterna-tive.F4. A Specification Checklist is included as a preface to, but not forming a part of, Standard Specification 117. The purpose of this Specification Checklist is to assist the Architect/Engineer in properly choosing and specifying the necessary mandatory and optional re-quirements for the Project Specification.PREFACE TO SPECIFICATION CHECKLISTP1. Standard Specification 117 is intended to be used in its entirety by reference in the Project Specification.Individual sections, articles, or paragraphs should not be copied into the Project Specifications since taking them out of context may change their meaning.P2. Building codes establish minimum requirementsnecessary to protect the public. Some of the require-ments in this Standard Specification may be morestringent than the minimum in order to insure the level of quality and performance that the Owner expects the structure to provide. Adjustments to the needs of a particular project should be made by the Architect/En-gineer by reviewing each of the items in the Specifica-tion Checklist and then including the Architect/Engi-neer’s decision on each item as a mandatory require-ment in the Project Specifications.P3. These mandatory requirements should designate the specific qualities, procedures, materials, and per-formance criteria for which alternatives are permitted or for which provisions were not made in the Standard Specification. Exceptions to the Standard Specification should be made in the Project Specifications, if re-quired.P4. A statement such as the following will serve to make Standard Specification ACI 117 an official part of the Project Specifications:Tolerances for Concrete Construction and Mate-rials shall conform to all requirements of ACI 117,Standard Specifications for Tolerances for Con-crete Construction and Materials, published by theAmerican Concrete Institute, Detroit, Michigan,except as modified by the requirements of theseContract Documents.Adopted as a Standard of the American Concrete Institute in November 1989 in accordance with the Institute’s standardization procedures.Copyright © 1990, American Concrete Institute. All rights reserved, includ-ing the making of copies unless permission is obtained from the copyright pro-prietors.*Chairman during initial development of this document.117-1117-2MANUAL OF CONCRETE PRACTICEP5. The Specification Checklist that follows is ad-Checklist consists of two columns; the first identifies dressed to each item of the Standard Specification the sections, parts, and articles of the Standard Speci-where the Architect/Engineer must or may make a fication and the second column contains notes to the choice of alternatives; may add provisions if not indi-Architect/Engineer to indicate the type of action re-cated; or may take exceptions. The Specification quired by the Architect/Engineer.MANDATORY SPECIFICATION CHECKLISTSection/Part/Article Section 2 - Materials2.2-Reinforcement Section 3 - Foundations3.1.1 Drilled piers Section 4 - Cast-in-place concrete for buildings4.5.4 Form offsets4.5.5 Floor finish4.5.5.1 For Section 4.5.64.5.5.2 For Section 4.5.7Notes to the Architect/EngineerTolerances for fabrication, placement, and lap splices for welded wire fabric must be specified by the specifier.Specify category of caisson. The designer should be aware that the recom-mended vertical alignment tolerance of 1.5 percent of the shaft length indicated in Category B caissons is based on experience in a wide variety of soil situations combined with a limited amount of theoretical analysis using the beam on elas-tic foundation theory and minimum assumed horizontal soil restraint. Designate class of surface (A, B, C, D):Class A -For surfaces prominently exposed to public view where appearance is of special importance.Class B - Coarse-textured concrete-formed surfaces intended to receive plas-ter, stucco, or wainscoting.Class C - General standard for permanently exposed surfaces where other fin-ishes are not specified.Class D -Minimum quality surface where roughness is not objectionable, usu-ally applied where surfaces will be concealed.Specify floor finish tolerance measurement method (either Section 4.5.6 or Sec-tion 4.5.7).Designate floor classification (15/13; 20/15; 30/20; or, 50/30).Designate maximum gap under a freestanding straightedge (1/2 in., 5/16 in., 3/16 in., or 1/8 in.).OPTIONAL SPECIFICATION CHECKLISTSection 1 - General1.1.2 Scope1.1.2 Scope 1.2.3 Requirements Tolerance values affect construction cost. Specific use of a toleranced item may warrant less or more stringent tolerances than contained in the specification. Such variances must be individually designated by the specifier in the contract docu-ments.Tolerances in this specification are for standard concrete construction and con-struction procedures. Specialized concrete construction or construction procedures require specifier to include specialized tolerances. AC1 committee documents cov-ering specialized construction may provide guidance on specialized tolerances. The tolerances in this Specification do not apply to special structures or procedures not cited in the document such as nuclear reactors and containment vessels, bins and silos, circular prestressed concrete tank structures and shotcrete.Where a specific application uses multiply toleranced items that together yield a toleranced result, the specifier must analyze the tolerance envelope with respect to practical limits and design assumptions and specify its value where the standard tolerances values in this specification are inadequate or inappropriate.TOLERANCESOPTIONAL SPECIFICATION CHECKLIST, continuedSection 2 - Materials2.2.3 Concrete cover2.3.2 Embedded itemsSection 3 - Cast-in-placeconcrete for foundations3.4.1.2 FootingsSection 4 - Cast-in-placeconcrete for buildings4.5.5 Floor finishSection 5 - Precastconcrete5.1.4 Camber5.3 PlanerelementsCONTENTS Section 1 - General, p. 117-4 1.1 - Scope1.2 - Requirements1.3 - DefinitionsSection 2 - Materials, p. 117-6 2.1 - Reinforcing steel fabrication2.2 - Reinforcement placement2.3 - Placement of embedded items 2.4 - Concrete batching2.5 - Concrete properties The tolerance for reduction in cover in reinforcing steel may require a reduction in magnitude where the reinforced concrete is exposed to chlorides or the environ-ment. Where possible excess cover or other protection of the reinforcing steel should be specified in lieu of reduced tolerance because of the accuracy of locating reinforcing steel utilizing standard fabrication accessories and installed procedures. Tolerance given is for general application. Specific design use of embedded items nay require the specifier to designate tolerances of reduced magnitude for various embedded items.Plus tolerance for the vertical dimensions is not specified because no limit is im-posed. Specifier must designate plus tolerance if desired.The procedures for specifying and measuring floor finish tolerances set forth herein are not appropriate for narrow aisle warehouse floors with defined traffic lanes de-signed for use by specialized wheeled equipment. Consult specific equipment man-ufacturers for their recommendations.The tolerances for precast concrete are intended to apply to all types of precast concrete construction cast onsite (including tilt-up) and offsite except as set forth below. Variations to these tolerances may be advisable after consideration of panel size and construction techniques required.Tolerances set forth herein are not intended to apply to plant production of pa-tented or copyrighted structural systems and/or elements. Designers, specifiers and contractors should contact the Licensors of such systems and/or products for ap-plicable tolerances.For members with a span-to-depth ratio equal to or exceeding 30, the stated cam-ber tolerance may require special production measures and result in cost premi-ums. Where feasible, a greater tolerance magnitude should be utilized where the span-to-depth ratio is equal to or greater than 30.Industrial precast products may not conform to the planar tolerances. Manufac-turers should be consulted for appropriate tolerances for their products.Section 3 - Foundations, p. 117-8 3.1 - Vertical alignment3.2 - Lateral alignment3.3 - Level alignment3.4 - Cross-sectional dimensions3.5 - Relative alignment117-3 Section 4 - Cast-in-place concrete for buildings, p. 117-94.1 - Vertical alignment4.2 - Lateral alignment4.3 - Level alignment4.4 - Cross-sectional dimensions4.5 - Relative alignment4.6 - Openings through membersSection 5 - Precast concrete, p. 117-105.1 - Fabrication tolerances in linear elements except piles5.2 - Fabrication tolerances for piles5.3 - Fabrication tolerances in planar elements5.4 - Erection tolerancesSection 6 - Masonry, p. 117-116.1 - Vertical alignment6.2 - Lateral alignment6.3 - Level alignment117-4 MANUAL OF CONCRETE PRACTICE6.4 - Cross-sectional dimensions6.5 - Relative alignmentSection 7 - Cast-in-place, vertically slipformed structures, p. 117-117.1 - Vertical alignment7.2 - Lateral alignment7.3 - Cross-sectional dimensions7.4 - Relative alignmentSection 8 - Mass concrete structures other than buildings, p. 117-118.1 - Vertical alignment8.2 - Lateral alignment8.3 - Level alignment8.4 - Relative alignmentSection 9 - Canal lining, p. 117-119.1 - Lateral alignment9.2 - Level alignment9.3 - Cross-sectional dimensionsSection 10 - Monolithic siphons and culverts, p. 117-1110.1 - Lateral alignment10.2 - Level alignment10.3 - Cross-sectional dimensionsSection 11 - Cast-in-place bridges, p. 117-12 11.1 - Vertical alignment11.2 - Lateral alignment11.3 - Level alignment11.4 - Cross-sectional dimensions11.5 - Relative alignmentSection 12 - Pavement and sidewalks, p. 117-12 12.1 - Lateral alignment12.2 - Level alignmentSection 13 - Chimneys and cooling towers, p. 117-1213.1 - Vertical alignment13.2 - Diameter13.3 - Wall thicknessSection 14 - Cast-in-place nonreinforced pipe, p. 117-1214.1 - Wall thickness14.2 - Pipe diameter14.3 - Offsets14.4 - Surface IndentationsSECTION 1 - GENERAL REQUIREMENTS 1.1 - Scope1.1.1 This specification designates standard toler-ances for concrete construction.1.1.2 The indicated tolerances govern unless other-wise specified.1.2 - Requirements1.2.1 Concrete construction shall meet the specified tolerances.1.2.2 Tolerances shall not extend the structure be-yond legal boundaries.1.2.3 Tolerances are not cumulative. The most re-strictive tolerance controls.1.2.4 Plus ( + ) tolerance increases the amount or di-mension to which it applies, or raises a level alignment. Minus ( - ) tolerance decreases the amount or dimen-sion to which it applies, or lowers a level alignment. A nonsigned tolerance means + or - . Where only one signed tolerance is specified (+ or - ), there is no limit in the other direction.1.3 - DefinitionsArris - The line, edge, or hip in which two straight or curved surfaces of a body, forming an exterior an-gle, meet; a sharp ridge, as between adjoining channels of a Doric column.Bowing - The displacement of the surface of a planar element from a plane passing through any three corners of the element.Clear distance - In reinforced concrete, the least distance between the surface of the reinforcement and the referenced surface, i.e., the form, adjacent rein-forcement, embedment, concrete, or other surface. Concealed surface - Surface not subject to visual observation during normal use of the element. Contract documents - The project contract, the project drawings, and the project specifications. Cover - In reinforced concrete, the least distance between the surface of the reinforcement and the outer surface of the concrete.Flatness - The degree to which a surface approxi-mates a plane.Lateral alignment - The location relative to a spec-ified horizontal line or point in a horizontal plane. Level alignment - The location relative to a speci-fied horizontal plane. When applied to roadways, bridge decks, slabs, ramps, or other nominally hori-zontal surfaces established by elevations, level align-ment is defined as the vertical location of the surface relative to the specified profile grade and specified cross slope.Levelness - The degree to which a line or surface parallels horizontal.Precast linear element - Beam, column, or similar unit.Precast planar element - Wall panel, floor panel, or similar unit.Project Specifications - The building specifications which employ ACI 117 by reference, and which serve as the instrument for making the mandatory and optional selections available under these and for specifying items not covered herein.Relative alignment - The distance between two or more elements in any plane, or the distance between adjacent elements, or the distance between an element and a defined point or plane.Spiral - As used in circular stave silo construction, is defined as the distortion that results when the staves are misaligned so that their edges are inclined while their outer faces are vertical.
