Aggregate Supplier in Gurgaon

Coarse aggregates or simply aggregates are medium grained crushed stone/ rocks majorly used in construction and are one of most mined materials in the world. 20 mm aggregates are of size greater than 4.75 mm and typically get classified as 20 mm.

They are obtained from natural disintegration or through artificial crushing of rocks in crusher machines. The maximum size of coarse aggregate should be 80 mm. It is majorly used in concrete elements with thin sections, closely spaced and heavy reinforcement for better strength and strong hold.

Aggregates belong to the class of inert granular materials such as sand, gravel, or crushed stone that, along with water and cement, is a necessary ingredient in concrete.

To have a good concrete mix, aggregates are required to be clean, hard, and strong while at the same time particles must be free of absorbed chemicals or coats of clay and other undesirable fine materials that may cause the deterioration of concrete with time.

Aggregates, in general, account for 60 to 75 percent of the total volume of concrete and perhaps lays the foundation of a strong base for it. Aggregates are divided into two categories – fine and coarse. Fine ones in general, consist of natural sand or crushed stone with most particles being able to pass through a 9.5 mm sieve. Coarse aggregates are a bit bigger in size and this category is defined as particles greater than 5 mm, but generally, the range is between 9.5 mm and 38 mm
