Cement Industry - VDZ

Cement is an inorganic, finely ground, hydraulic binder for mortar and concrete. The base constituent of modern construction cement consists of a mixture of 70 to 80 mass percent limestone and 20 to 30 mass percent clay. Depending on the chemical composition of the ex-traction site, corrective material such as iron ore or sand need to be added.

Comparative Study of Soil Grouting with Cement .

Cement slurry and cement-sodium silicate slurry are most widely applied for soil grouting reinforcement project. The viscosity change of cement slurry is negligible during grouting period and presumed to be time independent, while the viscosity of cement-sodium silicate slurry increases with time quickly and is presumed to be time dependent.

The production process for portland cement first involves grinding limestone or chalk and alumina and silica from shale or clay. The raw materials are proportioned, mixed, and then burned in large rotary kilns at approximately 2500°F until partially fused into marble-sized masses known as clinker. After the clinker cools, gypsum is added, and both materials are ground into a fine powder which ...
