ALAG (ALuminous AGgregate) is a synthetic calcium aluminate aggregate manufactured by the fusion of bauxite and limestone into a partially re-crystallized aggregate of approximately 40% alumina. It is essentially Fondu clinker, crushed and sized into grades commonly needed by concrete and castable formulators.
ALAG is a high density, impermeable, black angular aggregate with exceptional hardness. ALAG has a strong chemical affinity for calcium aluminate cements and, therefore, ALAG concretes utilizing calcium aluminate cement as the binder provide outstanding performance in applications requiring resistance as below;
