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
