How Cement Is Made

Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with shale, clay, slate, blast furnace slag, silica sand, and iron ore.

Cement Chemistry - an overview ScienceDirect Topics

Ordinary portland cement contains, apart from minor CaSO 4 2H 2 O, four main crystalline phases: tri-calcium and bi-calcium silicates (in cement chemistry referred to as C 3 S and C 2 S, respectively), tri-calcium aluminate (C 3 A) and tetra-calcium alumino-ferrite (C 4 AF), in very strict ranges of proportions, each of them playing a specific role in cement manufacture and/or use.

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.

2011-8-19  Modern Portland cement is termed 'Ordinary Portland Cement' (OPC) and is made by combining limestone or chalk (CaCO 3) with sand (SiO 2), clay and other materials (eg: Al 2 O 3, Fe 2 O 3, TiO 2) in a kiln at temperatures in the region of 1400-1500°C. 15 The mixture first undergoes decarbonation in which CO 2 is lost from the limestone to produce calcium oxide (CaO).
