Correlation of normal concrete compressive strength with destructive and non-destructive test methods.

An investigation has been made to perceive the correlation of normal concrete compressive strength between the destructive and non-destructive test method. The non-destructive method used Ultrasonic Pulse Velocity Test. Meanwhile, destructive method used a concrete compressive test. Testing the compressive strength of concrete using cylinder concrete samples. The cylinder concrete samples used in this study had a concrete mix design of 25 MPa and 30 MPa. Each sample was tested destructive and non-destructive to get the compressive strength value relationship. Based on the result, the regression model proposed to estimate the compressive strength of concrete is the first regression model which is f'ce=0,0037v1+12,346. The results are validated using column structure located in K2F Room on BINUS Syahdan campus. The validation result shows the estimated compressive strength from the linear regression model is higher than the projected compressive strength of the concrete column. [ABSTRACT FROM AUTHOR]
