When Portland cement is mixed with water, it undergoes a chemical reaction which leads to the hardening of the material. This process is called hydration and the results are the hydration products. The hydration process can be quantified by two characteristics; (1) the rate of reaction, and (2) the heat of reaction.

Portland cement consists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO2) and alumina (aluminum oxide, Al2O3). The lime is obtained from a calcareous (limecontaining) raw material, and the other oxides are derived from an argillaceous (clayey) material.
