Another essential raw material is gypsum, some 5 percent of which is added to the burned cement clinker during grinding to control the setting time of the cement. Portland cement also can be made in a combined process with sulfuric acid using calcium sulfate or anhydrite in place of calcium carbonate.

During cold weather, it may be necessary to heat one or more of the concrete materials (water and/or aggregates) to provide the proper concrete temperature as delivered. Due to the quantities and heat capacity of cement, using hot cement is not an effective method in raising the initial concrete temperature.

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.
