As per specification of BDS EN 197-1:2003, CEM-1, 52.5 N Crown Portland Cement is a cement prepared by mixing clinker 95-100% and gypsum 0-5%. This cement is also called Portland Cement (PC). This is obtained by intimately mixing together calcareous and argillaceous materials, burning them at clinker temperature up to about 1450 degree celsius and grinding the resulting clinker (calcined product) at required fineness and finally mixed with gypsum to obtain cement. This cement is a finely ground mixture of calcium aluminates and silicates capable of setting and hardening by chemical reaction with water. It is a binding material, which is used in engineering constructions.
Crown Cement is tested for soundness by the Le-Chatelier method and autoclave test.

Read MoreRaw materials are tested in this lab before they are imported and sample of cement are also tested each and every hour during production. For quality assurance cement is tested on various parameters. For this, the chemists of M.I. Cement Factory Ltd. conduct the compressive strength test making concrete/mortal cubes of different test age-3 days, 7 days and 28 days, as per ASTM C-150, and 2 days & 28 days as per EN (European Standard) at its laboratory. Therefore we can deliver the highest quality cement to our customers.
