The Effect of Aggregate Properties on Concrete

Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass. This hardening process continues for years meaning that concrete gets stronger as it gets older.

Concrete Composition & Hydration process of cement

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.

Cement and aggregates processing with HAZEMAG

Cement is a powdered substance made of calcined limestone, clay and silica that, when mixed with water, forms a paste that acts as a binder to hold fine sand and coarse aggregates, i.e. rock, in a mixture.
