Acid Resistant Mortar is made with over 42.5 grade ordinary Portland cement, sand and powder made of compact sand, quartzite and igneous rock, and adding suitable sodium silicate and sodium fluosilicate. Acid Resistant Mortar is mainly used as lining material, acid floor and acid protective layer.
Acid Resistant Mortar is a kind of special anticorrosive material with advantage of simple operation, good acid resistance, great impervious and hydrolytic resistance and low cost for kilns and furnace application.
Fineness: Residue on sieve for 900 holes per square centimeter is not greater than 1%. Residue on sieve for 4900 holes per square centimeter is not greater than 15%. Setting time: Initial set is not earlier than 30 minutes. Final set is not later than 8 hours. Acid stability: There is not crack, delaminating and damage after boiling for 1 hour in air and 40% sulfuric acid. Compressive strength: specimen is conserved for 28 days in air. Its compressive strength is greater than 30Mpa.
1. Lining of acid storage tanks and reaction vessels in chemical plants; 2. Sealing acid treatment equipment in laboratories; 3. Used in wastewater treatment facilities to protect pipes from acid wastewater erosion.
