建筑材料Building mterilsXX:TU5XX:建筑工程中使用的所有材料统称为建筑材料。
材料是保证土木工程质量的基础,所以建筑材料必须有一定结构上的使用性的物理特性。
首先,它们必须能够承担荷载或重量而没有永久性的变形。
当荷载作用在结构构件上时,构件将变形,那就是说绳索将被拉伸或梁将弯曲。
然而当荷载被移去时,绳索和梁将回到原始位置。
这种材料的特性就叫做弹性。
如果材料不是弹性的,那么在移去荷载后变形存在,重复加载和卸载最终增加变形到结构失去作用。
所有用在建筑结构里的材料如石材、砖、木材、铝材、钢筋混凝土和塑料在一定范围内的荷载作用下表现弹性。
如果加载超出了范围,两种情况会发生:脆性和塑性。
如果是前者,材料将突然破坏;如果是后者,在一定荷载材料开始屈服流动,最后导致破坏。
例如,钢材呈现塑性,石材是脆性。
材料最终强度由破坏时的应力决定。
建筑材料的另一个重要特性是是它的刚度。
这个特性由弹性模量决定。
应力(每单位面积上的力)与应变(每单位长度上的变形)的比率就是弹性模量。
弹性模量就是描述材料在荷载作用下的变形能力。
对于两种有相同面积且荷载相同的材料,弹性模量大的材料变形小。
结构用钢的弹性模量是铝的三倍,混凝土的10倍,木材的15倍。
混凝土concrete混凝土,简称砼,是指将集料胶结成整体的工程复合材料的统称。
通常讲的混凝土一词是指用水泥做胶凝材料,砂、石作集料:与水(加或不加外加剂和掺合料)按一定比例配合,经搅拌、成型、养护而得的水泥混凝土,也称一般混凝土,它广泛应用于土木工程混凝土是担待最主要的建筑材料之一。
它是由胶结材料,骨料和水按一定比例配制,经搅拌振捣成型,在一定的条件下养护而成的人造石材。
混凝土具有原料丰富,价格低廉,生产工艺简单的特点,因而使用量越来越大:同时混凝土还具有抗压强度高,耐久性好,强度等级范围宽,使其适用范围十分广泛,不仅在各种土木工程中使用,就是造船业,机械工业,海洋的开发,地热工程等,混凝土业是总要的材料。

托福building materials答案
托福building materials答案[ Paragraph 1 ] It is difficult to exaggerate the rad ical change that the new industrial world of the nineteenth century brought to architectural materials Since the beginning of architectural history, the same basic substances had been employed. They were provided directly by nature and used in their natural or near-natural state, only cut, shaped, and dried into the functional forms of timbers, stone blocks, and clay bricks. The exceptions were lime mortar and Roman concrete. Metals, which had the tensile strength t hat masonry materials lacked, were employed in minor and supplementary ways. Bronze was expensive as well as brittle Iron, the structurally more important metal, was available in limited quantities and uneven quality, and was too easily converted to rust by the elements. It was, therefore, restricted in use to things such as tie-rods and chains, and, along with bronze, to masonry clamps and decoration. Prior to the nineteenth century, the structural presence of iron in architecture was scarcely noticeable.1. According to paragraph 1, building materials in use before the nineteenth century wereA. not significantly changed from their natural formsB. strong and durableC. too expensive to use on a large scaleD. eventually replaced by lime mortar and Roman concrete2、in paragraph 1,the author discusses the properties of bronze and iron in order toA. contrast the qualities of bronze with those of ironB. explain why metals were not widely used in architecture before industrializationC. provide a reason why industrialization rad ically changed architectural materialsD. demonstrate that decorative materials were used in architecture before industrializat ion[ Paragraph 2] The Industrial Revolution changed all that Iron materials became available in such large quantities that they could play far more than a minor architectural role In 1800, the world production of iron stood at 825,000 tons, by 1830 itwas 1,825.000 tons, and nearly 40,000,000 in 1900-an increase of almost SO-fo ld over the century. The growth was not only in quantity, but quality as well. Iron, found bount ifully in Earth' s crust as an oxide, is a material of almost protean variability It is not simply pure or impure, but can be made hard or soft, brittle or ductile, strong or weak. These qualities depend on carbon content, freedom from impurities (slag), and heating and cooling treatments of the refined metal. Traditionally, three versions existed: cast iron, wrought iron, and steel. Cast iron is the crudest form, containing the most impurities and thus being extremely brittle. Wrought iron, because it includes almost no carbon, is highly malleable (hence its name), but also comparatively soft. The optimum material is steel, which incorporates a restricted amount of carbon for hardness but is otherwise free of impurities, giving it great strength, and which, as a result of tempering t reatments, is also malleable.3. According to paragraph 2, how did iron production change during the Industrial Revolution?A. As the level of production dramatically increased, the quality of the fin ished product became more and more variableB. New, higher-quality sources of iron were discovered in Earth 's crust.C. The distinction between pure and impure iron was replaced by distinctions among cast iron, wrought iron, and steelD. Better iron was produced through heating and cooling treatments, control of carbon content, and purification of the metal。
