Cement: Materials and manufacturing process

A ball mill is a rotating drum filled with steel balls of different sizes (depending on the desired fineness of the cement) that crush and grind the clinker. Gypsum is added during the grinding process to provide means for controlling the setting of the cement. The cement is bagged transported for concrete

Cement Production - an overview ScienceDirect Topics

In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section 25.3.2). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.

Cembrit Fibre Cement Products :: Cembrit

The fibre-cement manufacturing process was invented by an Austrian Ludwig Hatschek in the 1890’s. He combined, after 7 years of experimenting, cellulose, reinforcing fibres and cement in solution in water. This “slurry” was fed into a paper making machine, basically a cylindrical sieve or sieves rotating through the slurry. The solids are deposited on the sieve which on each rotation ...

Cement - Cement testing Britannica

The setting and hardening of a cement is a continuous process, but two points are distinguished for test purposes. The initial setting time is the interval between the mixing of the cement with water and the time when the mix has lost plasticity, stiffening to a certain degree. It marks roughly the end of the period when the wet mix can be molded into shape. The final setting time is the
