Acid resistant castable is also called refractory castable, which is one of the refractory material, and can resist the acid erosion, which is widely used in non-ferrous metallurgy, chemical industry, chimney, etc. Compared with other unshaped refractory, Acid resistant refractory castable has higher content of binding agent and moisture and greater liquidity. Unshaped refractory has a wide filed of application and can be used through pouring or ramming according to the choice of service conditions for materials and binding agent.
Acid resistant castable manufacturing process is simple without special equipment. Acid resistant castable has high mechanical strength and high quality. It is easy to construct through method of pouring. Acid resistant castables can be directly used into the engineering without firing. And acid resistant refractory castable can resist acid medium corrosion of 800 ~ 1200 ℃ can be pouring called refractory acid resistant castable. Refractory acid resistant castable is made with water glass as binder, acid or alkali acid refractory as aggregate and powder, and a small amount of coagulant. However, such castings are not resistant to corrosion by alkali, hydrochloric acid, hydrofluoric acid and high fat.
The general composition of acid resistant castable are: acid-resistant refractory aggregate (60-70%), powder (30-40%), and sodium fluorosilicate (13%-16%) as the hardening agent.

|Cold Crushing Strength (110℃×24h) Mpa||≥30|
|Cold Crushing Strength (1350℃×24h) Mpa||≥45|
Acid resistant castable is widely used in acid petrochemical plant and sulphuric acid plant.
Acid resistant refractory castable can be cast in lining of the body and also can be made into pre cast products. which is widely used for linings of various furnaces and kilns, and acid resistant castable is widely used in industrial furnace of metallurgical industry, petroleum industry, chemical industry, building materials and engineering industry for resisting high temperature erosion.
