2015-9-18 Crushed Sand vs. Natural Sand: Make the Right Choice! Dec 01, 2016 The presence of silt and clay in the sand reduces the setting time of cement and make concrete and mortar weak and holds the dampness. The requirement of cement is more. Water table level get reduced due to dragging of the sand from the get price

However, concrete that incorporates higher levels of sand compared to coarser aggregates will be weaker overall and cannot be used for structural applications or where support or load-bearing abilities are required.

Shukla and A K Sachan2 (2000) studied environmental hazardous stone dust utilization in building construction. It is found that partial replacement will not affect the strength and also solve the problem of disposal of stone dust.

Read More2020-11-3 The Production Process of Concrete: Concrete is constructed using cement mixed with an aggregate-- a grainy blend of materials such as stone and sand. After mixing, the concrete is poured into a mold and left to harden then use in building. The aggregates are sourced from a local body of water and crushed in a natural procedure.
