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.

The process of manufacture of this special cement is same as that of portland cement. The clinkers formed in the manufacture of cement are grinded with water repellent film substance such as Oleic Acid or Stearic Acid. These chemicals form a layer on the cement particle and does not allow water to mix and start hydration process in the
Sep 20, 2017 Besides South Africa, the most industrialised African country, and barely a few others, large-scale industrial manufacturing is practically nonexistent.
