Introduction

   The concrete test hammer is an instrument which is easy to use, for quick and approximate measurement of 

the resistance to pressure of manufactured concrete products. The principles on which it works are based on the 

rebound impact of a hammer on a piston which rests against the surface of the concrete products. The Greater 

the resistance of the concrete, greater is the rebounded impact. By reading this rebound impact on a scale and 

relating it to curves or table on graphs supplied with the instrument, the resistance to compression in MPA or 

PSI can be found.
