Alkali resistance castable

Introduction:

The alkali-resistant refractory castable is an alkali-resistant hydraulic castable made of refractory clay clinker and other aluminum siliceous materials as aggregate and powder, aluminate cement as binder, and suitable admixture added. It can be constructed by on-site vibration casting, spraying, etc.

Advantages:

Resistance to alkali corrosion

Application:

Industrial furnaces with alkali corrosion in cement, steel, nonferrous metals, glass, machinery, petrochemical and other industries.
