The document discusses the relationship between the rebound of an elastic mass and the compressive strength of concrete, noting that the rebound from a hammer on concrete surfaces correlates with their hardness. The rebound value, referred to as the rebound number or index, can be used to directly assess the compressive strength using an accompanying graph on the hammer.

Compressive strength of the concrete
- 1. About Compressive strength of Concrete
- 2. Compressive Strength of the Concrete • The rebound of an elastic mass depends on the hardness of the surface against which its mass strikes. When the plunger of the rebound hammer is pressed against the surface of the concrete, the Spring-controlled mass rebounds and the extent of such a rebound depends upon the surface hardness of the concrete. • The surface hardness and therefore the rebound is taken to be related to the compressive strength of the concrete. • The rebound value is read from a graduated scale and is designated as the rebound number or rebound index. The compressive strength can be read directly from the graph provided on the body of the hammer.
