Cement and Concrete: The Environmental Impact — PSCI

2020-11-3  The Production Process of Concrete: Concrete is constructed using cement mixed with an aggregate-- a grainy blend of materials such as stone and sand. After mixing, the concrete is poured into a mold and left to harden then use in building. The aggregates are sourced from a local body of water and crushed in a natural procedure.

How Concrete is Made - Portland Cement Association

How Concrete is Made. 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.

How concrete is made - material, manufacture, making,

The Manufacturing Process The manufacture of concrete is fairly simple. First, the cement (usually Portland cement) is prepared. Next, the other ingredients—aggregates (such as sand or gravel), admixtures (chemical additives), any necessary fibers, and water—are mixed together with the cement to form concrete.

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 ...
