摘要：In this paper, a series of compressive strength of core specimen’s to correlate the rebound hammerindices and UPSV results obtained from member of existing buildings. The combined method (SONREB) was used toquality control and strength estimation of the concrete. This combined method requires short time to obtain the results,it’s a non-invasive method and it does not affect the resistance of structural elements. The best fit equation of SONREBmethod for the determination of concrete compressive strength is obtained through processing correlation among thedata sets. Finally the investigation and comparison of experimental results of non-destructive tests and core strengthwith the help of statistical data obtained by testing of specimen as per recommended procedures by IS 13311:1992 andIS 516:1959 respectively. The use of the combined methods (SONREB) increases the accuracy of the estimation of thein situ concrete compressive strength.
