THE EFFECT OF COARSE AGGREGATE SIZE ON THE COMPRESSIVE STRENGTH OF CONCRETE

Abstract

This research was conducted with the aim of knowing the effect of the grain size of coarse aggregate with sizes of 40 mm, 20 mm and 10 mm on normal concrete compressive strength values. 10 mm coarse aggregate of 25.63 Mpa then the size of the 20 mm coarse aggregate experienced an increase in the concrete compressive strength value of 27.21 Mpa and for a 40 mm coarse aggregate size the concrete compressive strength value increased by a value of 31.25 MPa, from these results it can be It can be concluded that the grain size of coarse aggregate which has a large grain size has a greater compressive strength value than the coarse aggregate which has a small grain size.
