Crushed sand is a replacement for river sand in a concrete building. When Crushing hard granite stone produces manufactured sand. The manufactured sand (M-Sand) size is reduced to less than 4.75mm. ... Due to the higher costs of river sand, the lack of suitable crusher setup in some regions of the nation, such as West Bengal, might be a concern.
River-sand mining has risen dramatically in the last few decades to fulfil the need for concrete in the building sector. The sand in a river's bed preserves its environmental equilibrium (Farahani and Bayazidi, 2017).Excessive river-sand mining for use as fine aggregate in concrete is responsible for riverbed degradation, which causes a wide range of problems, …
