process of making cement
Laying the foundation for zero-carbon cement
Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to …

Cement: Materials and manufacturing process
• Chalk is porous and often has high moisture content that leads it to its use in the 'semi-dry/wet' manufacturing process of making cement. This particular process represents some 16% of total production. Shale • Shale is a pure sedimentary rock made of very fine silt, clay and quarz. Shale falls in the category of mudstones.

Everything You Need to Know About Portland Cement
Portland cement is a type of building material that is made from limestone, sand, clay, and other materials. The process of making Portland cement starts with the heating of limestone and clay in a kiln. The heated materials are then ground into a powder. This powder is mixed with water to form a slurry (a liquid mixture).
