     High strength light castable is made of aluminate cement, high alumina fine material, ceramsite and some additives. The product has light volume, high compressive strength, acid and acid gas corrosion resistance. Heat insulation, heat preservation, low water absorption and simple construction are ideal products for construction of alkali resistant parts under high temperature. Good workability, strong adhesive force, long initial setting time and construction operable time, fast strength growth, strong impermeability, no need of acidizing treatment, easy to ensure the dense and full mortar joints of masonry, which can significantly improve the air tightness, integrity of the lining wall and the anti-corrosion ability of the lining. It is an ideal cementitious material for the lining of high chimneys, high-temperature flue and air duct, as well as for petroleum and chemical industry Acid resistant projects such as acid pool and tank in nonferrous metallurgy and other industries. Acid resistant brick, acid resistant mastic and plastering fabric acid resistant brick, acid resistant mastic and plastering fabric are the refractory materials specially developed by our factory, which are suitable for thermal insulation of boiler chimney and heating network pipeline in power station. They are acid corrosion resistant, temperature resistant, heat-resistant and stable, and easy to construct.
