replacement of river sand with crushed rock sand in concrete production

PARTIAL REPLACEMENT OF NATURAL RIVER SAND WITH

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 %

What are the Materials for Replacement of Sand in Concrete

Crushed sand (Manufactured sand) is produced by crushing rock (as in the case of coarse aggregate) to give particle size and grading at par with river sand, the texture may differ using Vertical Shaft Impactor Machines. The percentage passing 150 microns of manufactured sand is relaxed to 20% (while that of natural sand is limited to 10%).

Influence of limestone waste as partial replacement

crushed sand can be mitigated by using a water reducing admixture. R. Ilangovana et al. [6] found that the natural river sand, if replaced by hundred percent quarry rock dust from quarries, may sometimes give equal or better than the reference concrete made with Natural Sand, in terms of compressive and flexural strength studies.

Experimental Investigation on the Effect of Replacement of

River sand is costly due to transportation, large scale depletion of resources and enforcement regulations. Quarry dust can be used as an alternative to the river sand. Cost analysis shows that there is 40% savings if quarry dust is used instead of sand. Illangoan.R [2000] [1] has done a study on 100% replacement of sand by quarry dust in concrete.

Crushed Sand vs. Natural Sand: Make the Right Choice!

It is recommended to use crushed sand. It is an economic and ecological alternative to natural sand. Crushed sand possesses properties similar to that of river and is a more sustainable construction material. Scientifically use of crushed sand will provide a long-term solution to construction industry to overcome shortage of river sand.
