Propriedades e Aplicações
Active Alumina is a hydraulic binder that promotes excellent performance in structural materials, due to its high modulus of elasticity, refractoriness, hardness, resistance to chemical attack and resistance at high and low temperatures. Accelerates cement hardening and provides high mechanical strength.
Its use is recommended for mortars that require fast drying and high resistance, refractory masses, grouts, concretes, etc.
