How Concrete is Made - The Portland Cement .

In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.

All in Aggregate. It is the aggregate composed of both fine aggregate and coarse aggregate. According to size All-in-aggregate is described as all-in-aggregates of its nominal size, i.e. 40mm, 20mm etc. For example, all in aggregate of nominal size of 20mm means an aggregate most of which passes through 20 mm IS sieve and .

Total Aggregate by cement ratio (A/C) decreases with increase in grade of concrete. For example, M20 grade of aggregate will have a higher A/C ratio than of M30; Higher the A/C ratio leaner the concrete mix, as cement content is lower. 2.A/C ratio may be fine tuned to get a concrete mix more workable.

Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6.

Importance of aggregate grading - Concrete

Importance of aggregate grading. Ideally coarse and fine aggregate should be graded in such a way as to minimise the voidage. After compaction the volume of the cement paste must be more than the voidage between particles. Underfilling will result in entrapped air and an unworkable mix.

The Effect of Aggregate Properties on Concrete

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.
