Abstract

A research on the testing of concrete elasticity has been done in order to measure concrete compressive strength  using a non destructive test based on sonic wave velocity. An equipment that was used for this research was a Sonic Wave Analyzer (SOWAN). In this research, concrete samples were formed in cylindrical shape with 15 cm diameter and 30 cm length. The compressive strengths of this concrete were 19  , 23    , and 25      ( ⁄ ). After that the time delay of sonic wave was measured. The research results showed that primary and secondary sonic wave velocity, elasticity, and compressive strenght were    = 3525 m/s,    = 1950 m/s,  23240  x N/ , and  24 x    ( ⁄ )  respectively. Based on the data, it was concluded that this non destructive test based on sonic wave velocity can be used to measure the concrete compressive strength, because the values obtained were comparable to the values obtained using the Universal Testing Machine (UTM) which is a destructive test.
