KUAT TEKAN BERDASARKAN HAMMER TEST DN COMPRESSION TEST PADA BENDA UJI SILINDER (Pengujian Laboratorium)

Abstract

There are several forms of concrete compressive strength test Method used between testing that is not destructive ( Non Destructive Test ), half damage ( Semi Destructive Test)and damaging the overall component – the component under test (Destructive Test). Compressive strength values obtained from the test hammer can not represent the Compressive strength of Concrete truth. The exact value required correlation between the Compressive strength of Concrete with a Hammer test and Compression test. the Compressive test is one of the key performance concrete in evaluating the strength of Concrete. Compression test has become standard to determine the overall quality of a structure that. The testing carried out in the laboratory. In fact , there are times where we needs to take the best directly to the structure in the field. Testing test Hammer is the one that is often conducted in the field in order to determine the qualiy characteristics of concrete. Data collection are done in three age groups 14day,21 day, 28 day withthe sample amounted to 6 cylinders at every age. This study proves that the Compressive strength valueis greather than the Hammer test, and the correlation between the Compressive test and Hammer test is 1,217 for the Compression test and 0,822 for Hammer test.
