Almost 35-45 % of fine aggregates are used by mass or by volume. All in Aggregate This type of aggregate includes both fine and coarse aggregates. They are represented in the form of nominal sizes like 20 mm, 40 mm, etc. Uses of Aggregates As we studied different types of aggregates, there are some uses of aggregates in construction.

It is the raw material for concrete. Sand, gravel, or crushed stone are used in the concrete mix and account for approximately 60% to 75% of the total volume of the concrete. It is used to bind concrete. Aggregates are classified into two categories fine and coarse aggregates. These two types of aggregates are used to make concrete.

On an average concrete contains 20 to 30% fine aggregates and 50 to 60% coarse aggregate. Different size of aggregates reduces the gap in concrete and makes concrete denser. Poorly graded concrete contains particles of the same size and leaving large voids in concrete (gaps).

Coarse aggregate is any material whose particles are anywhere from 3/8 inches and 1.5 inches in width. This is the size of aggregate often used in road construction. Fine aggregate: Most fine aggregates consist of crushed stone or natural sand. Most of the present particles must be able to pass through a 3/8-inch sieve.

The aggregates are divided into two major divisions by size- fine and coarse. The fine aggregates are sizes not larger than 5 mm while the coarse aggregate are sizes of at least 5 mm (Neville, 2003).

We are discussing coarse aggregate in this article. 1. Introduction Aggregates having a size of more than 4.75 mm are said to be coarse aggregate. In another word; aggregates retained on a 4.75 mm sieve are coarse aggregate. Coarse aggregate provides the volume to the concrete. It is used as a filler material in concrete, roads, etc. 2.

Aggregates larger than 4.75 mm in size are termed as coarse aggregates. These aggregates are obtained from stone quarries and stone crushers, the size between 4.75 mm to 80 mm. Good qualities of an ideal aggregate: These aggregate used for the construction of concrete and mortar must meet the following requirements.

The fine aggregates can be classified as coarse, medium and fine sands based on the fineness modulus. Fine Sand - Fineness Modulus of 2.2 to 2.6. Medium Sand - Fineness Modulus of 2.67 to 2.9. Coarse Sand - Fineness Modulus of 2.91 to 3.2. According to particle size distribution, IS: 383 -1970 has divided the fine aggregate in to 4 grading zones.

With most particles going through a 3/8-inch sieve, fine aggregates typically consist of natural sand or crushed stone. All particles larger than 0.19 inches are coarse aggregates but usually vary between 3/8 and 1.5 inches in diameter. Gravels make up much of the remaining coarse aggregate used in concrete with crushed stone.
