AluAX® Accelerating admixtures for sprayed concrete

AluAX is a solution of Na2Al2O4 with a Na2O/Al2O3 Mole Ratio of typically 1.80. AluAX is an economical source of high reactive aluminium of high purity.

AluAX is produced by reacting alumina hydroxide with sodium hydroxide. Our unique manufacturing process produces a material that is free of recipitates. This means that AluAX is stable over a wider range of handling and storage conditions.
