This paper deals with Experimental investigation for M-20& M25 grade of concrete having mix proportion 1:2.09:3.02 &1: 1.98:3.88 with water cement ratio 0.45 & 0.42 to study the destructive strength, grade of concrete, & rebound number. A result data obtained has been analyzed and compared with destructive results. A relationship between rebound numbers vs. destructive strength represented mathematically and graphically. Result data clearly shows that increase the strength of concrete in 28 days rebound number and destructive strength for M-20 & M25Grade of Concrete.

Keywords: Concrete mix, destructive strength, rebound number, grade of concrete.
