How Cement Is Made

Portland cement is the basic ingredient of concrete. Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common

The clinkering process is complete when all of the silica is in the C 3 S and C 2 S crystals and the amount of free lime is reduced to a minimal level. The cooling zone is where the clinker moves past the bottom of the kiln and the temperature drops rapidly and the liquid solidifies forming the other two cement minerals.

Most of the CO 2 footprint of cement is due to the decarbonation of limestone during the clinkering process. Designing new clinkers that require less limestone is one means to significantly reduce the CO 2 footprint of cement and concrete.

b. Rotary Kiln Cement Production

In contrast to static kilns, the material passes through quickly: it takes from 3 hours (in some old wet process kilns) to as little as 10 minutes (in short precalciner kilns). Rotary kilns run 24 hours a day, and are typically stopped only for a few days once or twice a year for essential maintenance. This is an important discipline, because heating up and cooling down are long, wasteful and
