混凝土强度回弹换算表
混凝土回弹值与强度关系换算表
混凝土回弹值与强度关系换算表
混凝土回弹值是一种用于评估混凝土强度的非破坏性检测方法。
回弹值是通过测量混凝土表面使用回弹锤敲击后的反弹高度来确定的。
根据混凝土回弹值和强度之间的关系,可以进行强度的估计。
混凝土回弹值与强度之间的关系
混凝土回弹值与强度之间存在一定的相关性。
然而,由于混凝
土的成分、配合比、养护条件等因素的不同,回弹值与强度之间的
关系并不是线性的。
为了将混凝土回弹值转换为强度估计,需要使用换算表。
本文
档提供了一份简单的混凝土回弹值与强度关系换算表,以便在实际
工程中使用。

请注意,该换算表仅供参考,实际结果可能会受到其他因素的影响。
在进行混凝土强度估计时,建议结合实际工程情况和其他测试方法进行综合评估。
结论
混凝土回弹值与强度之间的关系是复杂的,但通过使用换算表可以进行一定程度的强度估计。
然而,在实际工程中,建议结合多种测试方法和实际情况进行强度评估,以获得更准确的结果。
混凝土强度回弹换算表
混凝土强度回弹换算表一、混凝bai土回弹仪回弹值的计算方du法1、计算测区平均回弹值,zhi应从该测区的16个回弹值中剔除3个最大dao值和3个最小值,余下的10个回弹值按下式计算:10式中Rm—测区平均回弹值,精确至0.1;Ri—第i个测点的回弹值。
2、非水平方向时按下式修正:RmRi110iRmRmRa式中Rm—非水平检测时测区的平均回弹值,精确至0.1;Ra—非水平状态检测时的回弹修正值,按附表查询。
3、水平方向检测混凝土浇筑顶面或底面时按下式修正:ttRmRmRabbRmRmRatb式中Rm、Rm—水平方向检测混凝土浇筑表面、底面时的测区回弹值平均值;bRat、Ra—混凝土浇筑表面、底面回弹值的修正值,按附表查询。
4、当检测时回弹仪既非水平状态有非混凝土的浇筑侧面时,应先修正角度,再修正浇筑面。
上述的内容就是混凝土回弹仪回弹值的计算方法,此外,需要注意的是:混凝土回弹仪在检测时,回弹仪的轴线应始终垂直于结构或构件的检测面,缓慢施压,准确度数,快速复位。
二、举例子如下:泵送混凝土设计强度C50 柱子现场回弹值(这是其中一根,每根柱子只有1个测区)42 42 50 42 50 42 41 4242 40 41 42 51 50 42 42每层楼检测了6根柱子,其余5根的数据也差不多。
计算依据标准:《JGJ/T 23-2001 回弹法检测混凝土抗压强度技术规程》去掉3个最大值(51、50、50)、3个最小值(40、41、41)。
余下的10个回弹值,平均值:42.8 。
弹柱子是水平回弹,不用修正。
所有的测区数只有6个,不够10个,因此这六个测区选最小值进行评定。
碳化深度没有数据,设为0.5;(碳化深度大于2.0时,需钻芯)查附录A“测区混凝土强度换算表”,得45.7MPa。
如果为泵送混凝土,再按附录B“泵送混凝土测区混凝土强度换算值的修正值”进行修正。
这里设碳化深度为0.5mm,那么修正值为3.0MPa。

回弹法:
回弹法是用一弹簧驱动的重锤,通过弹击杆,弹击混凝土表面,并测出重锤被反弹回来的距离,以回弹值作为与强度相关的指标,来推定混凝土强度的一种方法。

混凝土强度回弹换算表
混凝土回弹仪的强度换算表如下:
混凝土回弹仪回弹值的计算
1.要计算调查区域的平均回弹值,应从调查区域的16个回弹值中删除三个最大值和三个最小值。
剩余的10个回弹值根据以下公式计算:RM是调查区域的平均回弹值,精确到0.1;RI是第i个测量点的回弹值。
2.在非水平方向的情况下,校正以下公式:RM RI 110 I RM RA,其中RM是非水平检测过程中测试区域的平均回弹值,精度为0.1;RA是非水平状态检测中的回弹校正值,可根据下表查询。
回弹测试仪原理:
混凝土回弹仪是一种弹簧驱动弹头锤并通过弹簧敲击棒敲击混凝土表面而产生的瞬时弹性变形恢复力,使回弹锤可以驱动指针弹回并指示弹跳距离。
回弹值(回弹距离与锤击前锤与杆之间距离的比率,以百分比计算)是与混凝土抗压强度有关的指标之一,可用来估计混凝土的抗压强度。
扩展数据:
有下列情况之一的,应定期维护回弹测试仪:
1.超过2000次弹丸攻击;
2.对测试值有疑问时;
3,钢砧设定值不合格;混凝土回弹仪
混凝土回弹仪的日常维护方法应符合以下要求:

2.用汽油清洁芯子的所有零件,尤其是中央导杆,子弹锤和弹簧杆的内孔和冲击面。
清洁后,在中心导杆上涂一层薄薄的时钟油或缝纫机油,其他部位不得上油;
3.清洁外壳的内壁,除去水垢,并检查指针的摩擦力应在0.5-0.8n之间;
4.请勿旋转尾盖上的固定调零螺钉。
5.不要制造或更换零件;
6.维护后,应按要求进行校准测试,校准值应为80±2。

经试验研究发现原2.2J回弹仪的能量太小,无法适应高强混凝土的检测。
一旦现场出现质量事故,无可靠方法解决。
自1996年以来通过大量的实验,终于研制成功既适合现场使用又能满足测强曲线精度要求的大能量(5.5J)回弹仪,在此基础上,通过大量混凝土试件与回弹仪的试验,找到了精度较好的测强公式,从而较好地解决了使用大能量回弹仪检测现场高强混凝土的问题。
由于回弹仪的标准状态是直接影响检测结果准确与否的关键,同时现场构件检测时尚有许多具体检测内容例如测区数量、布置、构件强度推定等需要规定统一的方法,因此为保证检测精度有必要制定规程。

回弹法:
回弹法是用一弹簧驱动的重锤,通过弹击杆,弹击混凝土表面,并测出重锤被反弹回来的距离,以回弹值作为与强度相关的指标,来推定混凝土强度的一种方法。
