Aggregate
Aggregate the raw material produced from natural rocks which solid, has good strength and can used widely in construction with some other ingredients.
Aggregate is combined with cement, sand and water to form the concrete. Aggregates gives strength and rigidity to concrete.
Aggregates gives volume, strength, stability, resistance to wear, resistance to impact and other physical properties to finished product.
Aggregates is also used in road construction, rail way construction, bridges, highways, and many other constructions
Why aggregates are important in concrete?
Aggregates in construction are highly versatile materials which used widely in different kinds of the projects. It is widely used in non-reinforced works, retaining walls, foundation works, RCC etc.
Aggregates in concrete also contributes to 60-80% volume of concrete. which is very huge. It gives bulking and mechanical strength to concrete and And it also decreases the cement and water consumption in concrete.
Aggregates in concrete makes the concrete hard, durable and compact.
Aggregates also important ingredient of concrete which induces mechanical strength to concrete.
Aggregates gives volume, strength, stability, resistance to wear, resistance to impact and other physical properties to finished product.
