摘要
Portland cements contain an AFm phase whose anion content is initially dominated by OH- (hydroxy) and SO42- (sulfate); variants such as those based on C(2)ASH(8) may occur in blended cements. In service conditions AF(m) phases may exhibit anion exchange, principally with carbonate, chloride, and additional sulfate. The chemistry, stability, and crystal chemistry of AF(m) phases are reviewed briefly. New data are presented on the role of 3CaOAl(2)O(3)0.5CaCl(2)0.5CaSO(4)10H(2)O, which, it is proposed, should be named Kuzel's salt after its discoverer. (C) 1999 Elsevier Science Ltd.
