The use of crushed rock sand as a partial replacement of river sand in concrete production was and 0.59 for 0 % to 100 % natural sand replacement. The slump ranged between 49 and 60 mm for 0 % to 100 % natural sand replacement. N/mm2. The effective natural sand (RS) replacement ranged between 0 and 60 % with the best results achieved at 20 %
The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%). As per design and economics, crushed sand can be used to partially or fully replace river sand from a concrete mix. The Availability of crushed sand is not a concern as it can be manufactured from rocks in any season.
The study of a partial and full replacement for natural sand of mortar and concrete by Crushed Rock Powder (CRP) is done For different proportions like; 20% 40%, 60%, 80% and 100% and the strength
Natural or River sand are weathered and worn out particles of rocks and are of various grades or sizes depending upon the amount of wearing. Now-a-days good sand is not readily available, it is transported from a long distance. So it is a need of the time to find some substitute to natural river sand. for crushed sand.
Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.
