Cement Production - an overview ScienceDirect Topics

Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln. Nowadays, almost all new plants are based on the dry process and many old wet plants are also remodeled to dry or semidry processes. Dry cement manufacture has three fundamental stages: preparation of feedstocks, production

Raw Material Substitution - Cembureau

The main raw material used in cement production has traditionally been limestone. Limestone is abundantly available, but over 60% of the industry’s CO 2 emissions are caused by transformation of limestone into lime, called “decarbonation”. Accordingly, part of the route towards a low carbon concrete-built environment can involve limestone substitution.
