STEPS USED IN MANUFACTURE OF PORTLAND CEMENT 5. Mixing the raw materials while burning in the kiln leads to the removal of water from raw materials and chemical reactions between oxides of the raw materials by fusion (the process of melting substances in a molten substance), forming cement clinkers. 6. The clinkers are cooled to about 150°F (51°C) and then pulverized (crushed/powdered).

The manufacturing process of Portland cement uses magnesia as a raw material in dry process plants. An excess amount of magnesia may make the cement unsound and expansive, but a little amount of it can add strength to the cement. Production of MgO-based cement also causes less CO2 emission. All cement is limited to a content of 6% MgO.

It is therefore the methodology to be used in the quality control of cement manufacture and the main topic of module 2 of the course. This use of statistical process control needs to extend far beyond the laboratory and composition testing of the materials. It needs to be extended to control the manufacturing conditions within the process.
