In any cement grinding circuit, it is necessary to grind clinker, gypsum, and sometimes other additives in the proportions required at a predetermined fineness. The fineness is usually defined by the specific surface area of the cement measured in m²/kg or cm²/g.
Gypsum plays a very important role in controlling the rate of hardening of the cement. During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process.
The last stage of making cement is the final grinding process. In the cement plant, there are rotating drums fitted with steel balls. Clinker, after being cooled, is transferred to these rotating drums and ground into such a fine powder that each pound of it contains 150 billion grains. This powder is the final product, cement. Stage 6
Because of the final grinding operation, the particles of cement are charged (the surface charge is measured as the Zeta potential). While C 3 S and C 2 S possess a negative zeta potential, C 3 A and C 4 AF particles are positively charged. Role of C 3 A
During the cement manufacturing process, upon the cooling of clinker, a small amount of gypsum is introduced during the final grinding process. Gypsum is added to control the "setting of cement". If not added, the cement will set immediately after mixing of water leaving no time for concrete placing.
The strength of cement is directly proportional to its fineness. Because, smaller the particle of cement, it offers a larger surface area and larger surface area gives more heat of hydration, larger area for bond hence faster the development of strength. However, the excess fine cement increases the cost of grinding and need more water in ...
