Cement Manufacturing Process. Cement is the basic ingredient of construction and the most widely used construction material. It is a very critical ingredient, because only cement has the ability of enhancing viscosity of concrete which in returns provides the better locking of sand and gravels together in a concrete mix.
How Is Cement Made? Step-by-Step Guide
Workers then dry the sheets of fiber cement slurry and press them together to form boards. Finally, they bake the fiber cement boards in high-pressure ovens called autoclaves that harden and cure the cement. From making cement to mixing and disposing of concrete, the right equipment can make the process faster and easier.
