Portland pozzolana cement shall be manufactured by mixing and inter-grinding Portland cement clinker, pozzolanic materials, and gypsum. The manufacturing process is approximately the same as ordinary Portland cement, which can be divided into four processes: raw material crushing, raw material grinding, clinker calcination, and cement grinding.
The raw materials are crushed and fed in the correct proportions into a grinding mill, where they are dried and reduced in size to a fine powder. The dry powder, called raw meal, is then pumped to a blending silo, and final adjustment is now made in the proportions of the materials required for the manufacture of cement.
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
