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 Works - Garage Builders

2021-11-11  Generally, concrete made using lower water-cement ratio makes a stronger concrete than when higher ratios are used. It is noticed that concrete made out of rough broken rock pieces is much stronger than concrete made using smooth pebbles. The reason is that the material should not result into more surface bondage area as this will increase the ...
