Schmidt rebound hammers for concrete strength and rock testing The original rebound test hammers for compressive strength and homogeneity assessment The Original Schmidt was invented and introduced into the market by Proceq in the 1950s Since that time it has become the world s first and most widely used instrument for non destructive estimation of concrete strength
c cube H = is the ratio of the compressive strengths of the wet conformity for the compressive strength of concrete based on compressive strength test results
This is a frequently employed nondestructive test to assess concrete uniformity and estimate in place compressive strength based on rebound numbers Rebound numbers on tested concrete surfaces are correlated to compressive strength according to the vertical horizontal or inclined direction of travel of the spring loaded plunger
Rebound is an effective non destructive measurement of the concrete compressive strength to within 20% and control of the uniform concrete quality in situ concrete and prefabricated structures
