混凝土极限强度与硬度的关系试论回弹法测试混凝土强度

摘要

形成混凝土结构的最终目的是能承受规定荷载和使用环境下的耐久性。混凝土极限荷载的大小受三种破坏模式的制约。回弹法检测混凝土强度是无损检测，又简便快捷，而颇受青睐，但回弹法仅仅是广阔混凝土结构平面上的一个点，是通过其本身硬度的反作用力（回弹值）来间接换算混凝土的强度。%The concrete structure is formed finally for bearing the specified load and gaining the durability under the use conditions. The limit load of concrete is restricted by three kinds of failure modes. The resilience method is the nondestructive test of concrete strength, simple and fast, and popular. However only a point in the large plane of concrete structure is tested with this method that is to use the reacting force （resilience value） of concrete hardness to calculate the concrete strength.
