Active Alumin
Chemical Denomination
Aluminum Oxide and Calcium Aluminate.
Properties and Applications
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.
Handling
Handling in a dry and well-ventilated place is required. Use dust mask and protective gloves
