Abstract

In this study, the performance of some non-destructive tests for the determination of compressive strength of concrete was investigated. Windsor probe penetration test, Schmidt hammer test and Ultrasonic test which are non-destructive test methods were carried out on hardened concrete. Besides of non-destructive tests, compressive strength of concrete was determined directly by using core samples taken by coring. Compressive strength of concrete specimens determined by destructive testing was compared by the values determined by non-destructive tests. As a result, Windsor Probe Penetration Test determined the compressive strength values with 2.5 % accuracy according to destructive core sample testing. This accuracy is about 5.4 % at the Schmidt hammer test and 3.5 % at the combined method.
