辽宁区域混凝土超声回弹测强曲线的应用研究

Applied Research of Ultrasound-rebound Concrete Strength Curve in Liaoning Province

多种因素均不同程度地影响超声回弹综合法检测混凝土强度的结果精度,本文对各种影响因素进行研究,探讨辽宁区域混凝土超声回弹测强曲线的适用条件,并在不同条件下进行了大量的试验,验证了辽宁区域的测强曲线的准确性。经实体工程检验证明,该曲线的应用大幅度提高了该检测方法的精度。

Many factors have influences on the accuracy of the results when the ultrasound rebound method is used to test concrete strength. In this article, factors are reasserted to find the applicable condi- tions of the ultrasound-rebound concrete strength curve in Liaoning province. A large number of tests are carried on to verify the accuracy of the Curve. Upon tests on the physical works, it is verified that the ap- plication of the Curve improves the accuracy of the ultrasound-rebound test method in Liaoning province.
