Manufactured sand (M-Sand) is used as a substitution to the river sand in construction. River sand is becoming a decaying resource in some parts of the year due to the lack of rains to collect the sand on the river beds. Manufactured sand can be considered as a by-product of the process of producing coarse aggregates.

How is concrete made? Traditionally, concrete is a mixture of coarse aggregates, fine aggregates, cement (which acts as a binder) and water. Sand was used as fine aggregates. But due to the scarcity of sand, we may use crushed rock or manufactured sand. The strength of concrete is very dependent on water-cement ratio.
