ALAG® is a synthetic calcium aluminate aggregate obtained from a fusion process. Its alumina content is approximately 40%. Its characteristic features are high density and exceptional hardness.
Combined with an aluminous cement, ALAG® displays strong chemical affinity and exceptional monolithic behaviour. This feature means that ALAG® concretes produce first class performance in terms of mechanical strength and resistance to abrasion, impact, high temperatures, thermal shock and many chemical substances.
