Acid Resistant Concrete

Acid Resistant Concrete is also called acid concrete. Acid concrete is a kind of refractory castable that can resist the acidic medium at 800-1200℃. It is made of acid and fire proof aggregates, about 60%, powders about 30%,  sodium silicate solution about 13%-16% with density of 1.38 1.42 g/cm3, plus sodium fluorosilicate as hardening agent. Owing to easy availability and low price of such raw materials, acid concrete is widely used in the thermal equipment of metallurgy, petroleum, light industry, power industry, chemical industry, farm chemicals, food, building material, electrical and mechanical industrial kiln and thermal equipment, etc.

    Being a kind of monolithic refractory, acid proof castable is the same as the others, it can be used directly without firing. In addition, compared with the other unshaped refractory, acid castable has good mobility with more bonding agents and water. It can be used as the pouring lining body, and be made into precast blocks by method of pouring and vibration. It is simple in process because it doesn’t need special equipment. With high mechanization degree, easy construction, good material utilization, and high strength at room temperature, it can be installed on the thermal equipment at site.

    What is Acid Resistant Concrete

    Acid resistant concrete belongs to monolithic refractory, which is featured with resistance to the corrosion of strong acid or acidic slags, high porosity, high temperature mechanical properties, strong plasticity, good thermal shock resistance, good wear resistance, and good liquidity. And due to the slow-release expansion agent, such material has good integrity, avoiding cracks at high temperature.
