Cement, sand, aggregates and water are the components of concrete. A mixture of Portland cement and water is called a pasta. So, concrete can be described as a mixture of paste, sand, and aggregates, although sometimes rocks are used in place of aggregates. The cement paste coats the surface of the fine and coarse aggregates when mixed

In cement, gravel and sand together provide the right support when the mix hardens. The materials in asphalt provide a similar role. Aggregate may be combined with other materials to produce concrete. Aggregates find there way into several applications. For example, gravel is used to pave some road types and provides support for railroad tracks.

Aggregates can be defined as the crushed stone which used in concrete. Aggregate in concrete occupied about 70 – 80 % of the total volume which provides the main body to concrete. Aggregate makes concrete strong and durable when mixed with cement, sand, and water.

Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete.

Definition. A concrete made from a mixture of lime, sand, and gravel is said to be as lime concrete. It was widely used before the lime was replaced by Portland cement. Lime as the first cement: Since long, Lime has been used to make things like plaster and mortar. Lime is usually made by burning of limestone.

Aggregate is one of the three principal ingredients of concrete. It comes in different sizes and starts from sand and moving up to larger particles. These particles fit together to produce a dense material approx 70% of the volume of the concrete is aggregate. So in concrete, these pieces of aggregate are bound together by a mixture of cement

Natural aggregate consists of manufactured crushed stone and sand created by crushing bedrock, or naturally occurring unconsolidated sand and gravel. It is a major component of asphalt and concrete and is required in streets, highways, railroads, bridges, buildings, sidewalks, sewers, power plants, and dams—just about every part of the built environment.

Only cement is unusually used; it is used to bind coarse and fine aggregate to produce mortar and concrete. The cement is mixed with fine aggregate to have mortar for plaster and masonry, and with sand and coarse aggregate to give concrete..

Multiply the same with the required dry volume of the concrete you will get the aggregate required in volume which has to be converted to weight.

''Cement'' vs. ''Concrete'' This distinction is not a new one; we have citations from over a century ago in which writers take care to observe (or admonish) that concrete and cement are not synonymous (the reasoning being that cement is one of the parts of concrete)..
