ABSTRACT:
Additives for high alumina cement compositions are proposed. The additives are effective to reduce or prevent the deleterious conversion of hexagonal calcium aluminate hydrates to cubic hydrogarnet in the high alumina cement compositions. The additives comprise 80-99 wt. % of a siliceous pozzolan and 1-20 wt. % of an inorganic sodium or potassium salt.
