ROLE OF AGGREGATES IN THE CONCRETE
The Portland cement concrete is a simple material in appearance but has a very complex internal nature. The versatility durability, and economy of concrete have made it the world’s most used construction material.
Concrete is a mixture of three components: Portland cement, aggregates and water.
Portland cement and water forms a paste that hardens due to chemical reaction between cement and water. The paste acts as glue that binds the aggregates composed of sand and crushed stone into a solid rock-like mass.
The quality of the past and the aggregates dedicates the strength of the concrete.
Fine aggregate that is Sand (lesser than 4.5 mm size) and Coarse aggregate, which refers to the Crushed aggregate (greater than 4.5 mm size, makes up 70% – 80% of the total volume of the concrete. Therefore selection of the aggregate is most important. Aggregate must be of adequate strength, proper gradation and durable.
Concrete usually has good workability as long as concrete ingredients are used in proper propositions and an adequate aggregate gradation.
