How Cement Is Made

Bricklayer Joseph Aspdin of Leeds, England first made portland cement early in the 19th century by burning powdered limestone and clay in his kitchen stove. With this crude method, he laid the foundation for an industry that annually processes literally mountains of limestone, clay, cement rock, and other materials into a powder so fine it will pass through a sieve capable of holding water.

Preparation of cement raw materials. Alite (approximately Ca 3 SiO 5) provides almost all the "early strength" (strength up to seven days of curing) of cement and a moderate amount of late (>7 days) strength. Belite (approximately Ca 2 SiO 4) provides very little "early strength" and a large amount of late strength.So it can be seen that these small compositional changes have a large effect
