Aggregate : Its Types And Uses

The quality of the concrete and the amount of cement required are significantly influenced by the size and form of the aggregate. It also affects the concrete's resilience and strength. A fine aggregate is an aggregate with a size less than 4.75 mm, whereas a coarse aggregate is one with a size greater than 4.75 mm.

Effects of Aggregate Properties on Concrete

Variation in the size of Aggregates changes the water demand, cement content, micro-cracking (strength) in concrete. It also effects pumpability, and durability of concrete. Grading of aggregates depends on the proportions of coarse and fine aggregate. If grading of aggregate is varied, it also changes cement paste content (cost economy), workability of the mix,
