Rebound Hammer Testing (Schmidt hammer) Introduction The strength of concrete is generally governed by the strength of the cement paste. Measurements of the strength of the paste can therefore provide a reasonable assessment of the strength of the concrete.This strength can be determined by inference from the elasticity of the concrete.
Rebound Hammer Test Procedure for Concrete Hardness

The uses of the rebound hammer are given in Section 5.1 of C805, which states that "this test method is applicable to assess the in-place uniformity of the concrete, to delineate regions in a structure of poorer quality or deteriorated concrete, and to estimate strength."
