Raw materials Raw materials used for concrete blocks manufacturing are- powdered portland cement, water, sand, and gravels. The concrete mixture for the blocks has a higher percentage of sand and a lower percentage of gravel and water. Light-weighted blocks are made by replacing sand and gravel with expanded clay, shale or slate.

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.
