1. The coarse aggregates should be properly graded, and the gradation becomes more and more important as we increase the maximum size of coarse aggregate because of greater voids, which needs to be filled to attain the desired compressive strength. As void fraction increases on increasing the size of aggregates. 2.

Aggregate is classified as two different types, coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve), while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.

Concrete is a mixture of cement, water, coarse and fine aggregates with or without chemical and mineral admixtures. As aggregate covers 75 percent of the volume of concrete, for HSC, high-strength well-graded aggregate is essential. The presence of different sizes of aggregate (well-graded) in appropriate proportions is important to reduce void.
