Abstract
High alumina cement (HAC) is made by fusing a mixture of aluminous and calcareous materials low in silica, and grinding the resultant product to a fine powder. J. Bied, at the Pavin de Lafarge Company, obtained a patent for high alumina cement in 1908. HAC and its products have many desirable characteristics superior to those of portland cement, such as rapid hardening, high chemical and fire resistance. These encouraged the use of high alumina cement concrete in certain engineering applications. Conversion of the hexagonal hydrates (CAH IO or C2AHs) to cubic hydrogarnet (C3AH6) has however been a major problem limiting its use. It is primarily responsible Jar the retrogression of strength and durability of HAC concrete.
