Cement Chemistry Arthur Harrisson

The clinker chemistry model as commonly used starts with the premise that the essential ingredients of cement clinker are the four oxides; SiO 2, Al 2 O 3 , Fe 2 O 3 and CaO which, when heated to approximately 1450 C in the cement kiln, form the four compounds; Ca 3 SiO 5 , Ca 2 SiO 4 , Ca 3 Al 2 O 6 and Ca 2 AlFeO 5.

2 days ago The cement industry is responsible for seven per cent of global CO 2 emissions. It released 570Mt of the greenhouse gas last year. That is equivalent to driving an old car to the moon and back 4000 times and makes it the second-most polluting industry after steel. Progress in …

How Concrete Is Made Portland Cement Association

How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete. Within this process lies the key to a remarkable trait of concrete: …
