Rebound Hammer (Schmidt Hammer) GBG
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 strength can be determined by inference from the elasticity of the concrete.

What is an Impact Test? Definition from Corrosionpedia
The impact test is a method for evaluating the toughness, impact strength and notch sensitivity of engineering materials. Engineers test the ability of a material to withstand impact to predict its behavior under actual conditions. Many materials fail suddenly under impact, at flaws/cracks or notches.
IMPACT STRENGTH OF BRITTLE MATERIALS (ROCKS)
Test AIV (Aggregate Impact Value, SS 1974) The AIV (Aggregate Impact Value) is a standard test procedure by which the impact strength of aggregates is tested. Just like in Protodyakonov's test, the material used consists of irregularly shaped particles of the 14 + .
Aggregate Impact an overview | ScienceDirect Topics
Table presents the statistical data of the LA abrasion mass loss, aggregate crushing value (ACV) and aggregate impact value (AIV) obtained from 307 RA samples. As expected, the LA abrasion results suggest that the resistance to fragmentation of RA, in descending order, is RCA, MRA and RMA. However, this trend is not clear in the case of AIV and ACV.
