Cement is a cementing material resembling a natural stone quarried from portland in the u.k. It is made by grinding the raw materials into a very fine powder, mixing them intimately in predetermined proportions and burning them in a large rotary kiln at a temperature of about 1400 c. The clinker is cooled and ground to a fine powder, with some g.p.
