the influence of surface crudity of coarse aggregate to concrete strength

Abstract


The aim of this research was to find out the influence of  surface cruduity  value of coarse aggregater  to pressure strength  of concrete. The water ratio  that aplicated was 0,5. The percentation of surface cruduity  value  were 100%, 50%, and 0%  of the specimen. 9  cylinders of 150 x 300 mm specimens  had been tested. It was showed the surface cruduity  value  to the concrete cause  the strengths gettinglower as the percentation getting smaller (average 12 %)
