Acid Resistant Bricks
We manufacture Acid Resistant Bricks, which are brown/Grey in colour for IS-4860 and white in colour for IS-4457 standard. The colour of the bricks does not have impact on the performance of the bricks. These bricks have good density and low water absorption and low porosity. Very high cold crushing strength, High resistance to strong acids (except hydrofluoric acid) and partial resistance to alkalies are the important technical parameters of these bricks. These bricks are used in various industrial applications like Chemical Storage Tanks, Absorption Towers, Process Tanks, Flooring, vessels, Chimney lining etc. in Chemicals, Dyes and Intermediates, Alkalies, Fertilizers, Petrochemicals, Paper, Power and Steel Plants, and many more.
The Different types of Acid Proof Bricks have been mentioned further with different laboratory details.
We are only manufacture of Shape, Block, Special Size Acid Proof Bricks.
