Abstract

CA and CA2 are the principal anhydrous constituents of calcium aluminate cements. Once it hydrates, Crystals of CAHIO forms at low temperatures while C2AH8 at higher temperatures. Both hydrates converts to C3AH6 under certain circumstances. There are two proposed mechanisms for the beginning of the crystallization of cements. a) When Water is mixed with cement a suspension is formed and the solid begins to dissolve. By the time that the water has become saturated with calcium and aluminate ions, it is already super- saturated with respect to the formation of various calcium aluminate and alumina hydrates. These hydrates nucleate and grow, allowing more anhydrous cement to dissolve into the solution. This through- solution mechanism may lead to the formation of a strong microstructure of interlocking hydrate crystals.b) Once cement hydrates a kind of gel forms on the surface of the grain that depending on the temperature of hydration, the composition of the gel varies. At low temperatures (less than 20oC) it is calcium aluminate gel, while at higher temperatures it is reach from THE aluminum compounds. After the gel forms, the gydrates start to nucleate and growth of the crystals takes place and cenents sets.The mechanism of hydration was investigated by Transmission Electron Microscope and X - ray microanalyses.Results confirmed the hydration through the gel formation.
