proportions were higher than those of conventional concrete by using natural sand as fine aggregate ([2], [5], [7]-[14],[16]). However, it was found that workability of the concrete mixes decreased with an increase in percentage of M-sand as fine aggregate. It reveals that higher water requirement for concrete when M-sand
Large rocks (often limestone) are processed in a stone crusher to make smaller pieces. Is Sand Coarse or Fine? Sand is a granular material made up of fine rock particles. Sand is a naturally occurring, finely divided rock, comprising particles or granules ranging in size from 0.0625 (or 1⁄16) to 2 millimeters. [/su_box]
