混凝土硬化后其表面硬度与抗压强度之间有一定的相关关系。在混凝土质量表里基本一致的前提下,通过回弹仪测得的混凝土表面硬度来推算其强度,是目前我国基建部门比较广泛采用的非破损测试混凝土强度的方法之一。影响回弹法测强的因素,实际上就是 There is a certain correlation between the surface hardness and the compressive strength of concrete after hardening. Under the premise that the concrete quality table is basically the same, the strength of the concrete surface measured by the rebound meter is used to calculate the strength of the concrete. This is one of the methods widely used in China’s infrastructure sector to test the strength of concrete without damage. The factors that influence the rebound method’s strength measurement are actually
