Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called

Instant chilling process is a physical method, which modifies the properties of steel-making slag for utilization in the cement industry (Montgomery and Wang, 1991, 1992). It is done in four stages. The first is air cooling where the molten slag is placed on shallow plates to a bed thickness of approximately 100 mm and air cooled for 4 minutes. This is followed by an initial water cooling

Cement Manufacturing Process Phase 1: Raw Material Extraction. Cement uses raw materials that cover calcium, silicon, iron and aluminum. Such raw materials are limestone, clay and sand. Limestone is for calcium. It is combined with much smaller proportions of sand and clay. Sand & clay fulfill the need of silicon, iron and aluminum.

Key strategies to cut carbon emissions in cement production include improving energy efficiency, switching to lower-carbon fuels, promoting material efficiency (to reduce the clinker-to-cement ratio and total demand) and advancing process and technology innovations such as CCUS. The latter two contribute the most to direct emissions reductions in the Net Zero Emissions by 2050 Scenario.
