Cement results from heating limestone, silica, clay, and other materials in a kiln at 2,700°F. This process, known as calcination, produces clinker. The clinker is then ground into a fine powder, resulting in cement. According to the Global Cement Report, 92% of global cement production in 2020 was Portland cement.
