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 ...
The kiln is at the heart of the manufacturing process and in order to heat the materials, a 2,000°C flame is required. Once inside the kiln, the raw meal is heated to around 1,500°C. At this temperature, chemical reactions take place to form cement clinker.
When water is added to this mixture, the chemical reaction hydration begins. Concrete does not harden because of evaporation. It hardens because of hydration. The five major compounds in Portland cement are tricalcium silicate, dicalcium silicate, tricalcium aluminate, tetracalcium aluminoferrite and gypsum.
