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. When determining the strength of normal concrete, most concrete aggregates are several times

This is the most common classification, where in two types of aggregates are distinguished: (Fine and Coarse). (i) Fine Aggregates. In the Fine Aggregates, the grain-size lies between 4.75 mm and 0.15 mm. In other words, these pass-through from sieve with the mesh size of 4.75 mm and are retained on a sieve of 0.15 mesh size. Sand is the most universally available natural Fine Aggregate. (ii
