Effects of Aggregate Properties on Concrete .

· Variation in the size of Aggregates changes the water demand, cement content, microcracking (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,
