Along with appliance and spread of High Strenght concrete and commercial pumping concrete, traditional curve for ascertaining concrete strength by rebound method is not right.
随着高强混凝土和商品泵送混凝土的应用和推广,传统的回弹法测强曲线,已不适用于现代的商品混凝土。
The accuracy of the curve is tested and verified by the practical engineering, and the curve can be used as the curve for early-age ground slag concrete strength by rebound method in Zhengzhou.
经工程实践验证了该曲线的测试精度,建议可作为郑州市早龄期磨细矿渣混凝土回弹法的专用测强曲线。
The rebound method is a nondestructive testing method which can test the concrete compressive strength, and it is very convenient and dependable.
