Rebound Hammer Test

Rebound Hammer Test is done to find out the compressive strength of concrete by using Rebound Hammer as per IS:13311 (Part 2) : 1992. 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 pring-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.

 

Core Cutting Test on Concrete

This is a partially destructive test that is used to co-relate the various other properties of the concrete viz. UPV, electrical resistivity, rebound number etc. It is customary to take cores of 4 inch diameter for compressive strength determination.Concrete core drilling for strength determination is again dependent upon various factors for reliability. The conversion of concrete core (typically 3 or 4 inch diametercore) strength into 150 mm saturated cube strength depends upon :

  • effect of coring
  • shape factor
  • size effect
  • direction of coring w.r.t. placing of concrete
  • h/d ratio

With so many factors contributing to the final 150 mm saturated cube strength, the strength variation may be + / – 10% – 15%. However, it can be used to confirm the results of UPV differing largely in the values & also for co-relation. Hence the UPV & core results should be judiciously used, interpreted & co-related.



Paint Coating Testing
