Aggregates - Portland Cement Association

Aggregates. Aggregates are inert granular materials such as sand, gravel, or crushed stone that, along with water and portland cement, are an essential ingredient in concrete. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the ...

Cement Concrete

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

The aggregates consist of sand and gravel which are also tested prior to adding to cement. Due to its weakness in tensile strength, reinforcements are commonly used within the building blocks during the moulding/setting of cement concrete. The reinforcement materials are made in the shape of steel bars commonly called TMT.

Cement paste content and water absorption of recycled ...

2013-7-3  The amount of coarse aggregates in a typical concrete being of the order of 1,000 kg/m 3, this means that the water absorption between the end of mixing and casting should not be higher than 1.5 %. It can moreover be expected that high 24 h absorption values are representative of a high amount of porous cement paste.
