Cement Chemistry - The Concrete Portal

Cement contains highly soluble alkali oxides (Na2O and K2O). The dissolution of these compounds is responsible for the high alkalinity (pH 12 – 13) of the pore solution. Thus, the hydration of cement actually takes place in the pore solution, and not in water. Dormant Period

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.

Cement : Manufacture, Chemical Composition, Heat of Hydration

Manufacture of Portland Cement Step 1 – Quarrying Limestone and a 'cement rock' such as clay or shale are quarried and brought to the cement works. These rocks contain lime (CaCO3), silica (SiO2), alumina (Al2O3) and ferrous oxide (Fe2O3) - the raw materials of cement manufacture. Step 2 - Raw material preparation To form a consistent

CEMENT RAW MATERIALS - International Cement Review

Cement is a manufactured product made by blending different raw materials and firing them at a high temperature in order to achieve precise chemical proportions of lime, silica, alumina and iron in the finished product, known as cement clinker. Cement is therefore essentially a mixture of calcium silicates and smaller amounts of calcium aluminates that react with water and cause
