| 摘 要： | 通过对14d、28d360个商品混凝土试块回弹及抗压试验,在大量试验数据的基础上,统计混凝土表面回弹值与混凝土抗压强度之间的关系。经回归分析,推断出适用于龄期为14d、28d的地区回弹测强曲线,并与相应混凝土构件的回弹试验作对比来验证所建立的回弹测强曲线精度。结果表明,该曲线为更好地推算本地区混凝土检测提供了有关依据。

| Abstract: | 360 concrete specimens (14 d and 28 d) were studied with the test for rebound and compression strength. The statistic relationship between the concrete's rebound value and compression strength of concrete is found. On the basis of the statistic relationship,the concrete's rebound-strength curve (14 d and 28 d)is established and proved by concrete member's test for rebound. The result is shown that this curve can serve as the foundation for the inspection of concrete. |
