PROPERTIES OF AGGREGATES FOR CONCRETE

Approximately 75% of the volume of concrete is occupied by aggregates, so quality of aggregates plays an important role in determining properties of concrete. Aggregates are chemically inert, solid bodies held together by the cement. Aggregates come in various shapes, sizes, and materials ranging from fine particles of sand to large, coarse rocks.

Construction aggregate

Construction aggregate, or simply aggregate, is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.

In concrete works, sand is used as a fine aggregate.

Types Of Aggregates

b. Crushed Stone Sand developed by crushing the hard stones. c. Crushed Gravel Sand, developed by crushing the natural gravel. Fine aggregates are provided for building up thin-wall and traditional reinforced concrete structural elements. Because of its fine grained structure, it is mostly found in highway and airfield construction.

Effect of Aggregates on the Properties of Concrete

It is judged by the surface of a crushed concrete. If in a crushed concrete specimen, larger numbers of aggregate particles are seen pulled out from their sockets and some of them seen fractured or broken right through, then the bond is called good. Greater number of crushed aggregate particle suggests weaker aggregate.

Overview

The fine and coarse aggregates generally occupy 60% to 75% of the concrete volume (70% to 85% by mass) and strongly influence the concrete's freshly mixed and hardened properties, mixture proportions, and economy. Fine aggregates (Fig. 1) generally consist of natural sand or crushed stone with most particles smaller than 5 mm (0.2 in.).

Uses of Aggregates

Concrete aggregates are composed of geological materials such as gravel, sand and crushed rock. The size of the particles determines whether it is a coarse aggregate (e.g. gravel) or a fine aggregate (e.g. sand). The resulting concrete can be used in its natural state or crushed
