Cement Manufacturing Process - Civil Engineering

The raw cement ingredientsneeded for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches. Secondary crushers or hammer mills then reduce them to even smaller size of 3 inches. After that, the ingredients are prepared for pyroprocessing.

Concrete Production - an overview | ScienceDirect Topics

The cement carbon footprints are issued from two major sources, the decarbonation of lime during the burning process and emissions resulting from the production of heat necessary to increase the temperature up to 1500°C (Fig. 15.3). Some minor emissions can also be attributed to transportation, grinding of raw materials and clinker.
