Comparison of Compressive Strength of Hardened Concrete Using Schmidt Rebound Hammer and Conventional Testing Method
Testing of concrete plays a crucial role in controlling the quality of cement in concrete works. Methodical testing of the raw materials, the fresh concrete and the hardened concrete is an indistinguishable part of any quality control program for concrete that helps to attain higher efficiency and prominent assurance of the performance of the concrete in respect to both strength and durability. The following work proposes a study showing variation in the magnitudes of the compressive strengths as obtained from NDT using Schmidt rebound hammer and DT using CTM (compressive testing machine). Concrete cubes of 150 mm × 150 mm × 150 mm size were collected with a concrete mix of grade 25 and 30 N/mm2. 66 cubes were casted and used for the study of variation obtained in the values of compressive strength using NDT and DT, which was determined to be ranging from 0 to 15% with respect to DT for most of the cube samples. The result obtained proposes that using Schmidt rebound hammer as a non-destructive test to check the compressive strength of the hardened concrete is reliable.
