Stage of Cement Manufacture. There are six main stages of the cement manufacturing process. Stage 1: Raw Material Extraction/Quarry The raw cement ingredients needed 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 into smaller …

Large amounts of energy are consumed during the manufacturing of cement especially during the calcination process which also emits large amounts of CO2. A large part of the energy used in the making of cement is released as waste heat. A process to capture CO2 by integrating the recovery and utilization of waste heat has been designed. …

Step 1 - Site Work. Before concrete can be poured, the site needs to be prepared to reduce the chance of heaving from expansive soils and frost. On small projects, use hand to tools to clear the area of all grass, rocks, trees, shrubs, and old concrete, exposing bare earth. Earth moving equipment speeds up the process, especially for large pours.
