Focusing on Cement Manufacturing Process and its History
The manufacturing of Portland cement is the most common type of cement formation which is used in the construction sector. It is a type of hydraulic cement invented by Joseph Aspdin of England in 1824. It was produced from a mixture of limestone and clay. It got its name due to its high resemblance to the Portland stone in England.

Manufacturing of Portland Cement – Process and Materials
The manufacture of Portland cement is a complex process and done in the following steps: grinding the raw materials, mixing them in certain proportions depending upon their purity and composition, and burning them to sintering in a kiln at a temperature of about 1350 to 1500 ⁰C. During this process, these materials partially fuse to form nodular shaped clinker by …

Cement Production
Manufacturing cement at the Lafarge Seattle plant is by a "wet process". As a result, raw materials are mixed with 30 to 40% water during grinding to form well mixed slurry. This wet process is advantageous due to the increased compatibility with wet climates and more uniform blending of raw materials prior to the kiln, along with lower ...
