High strength wear-resistant castable is composed of high strength aggregate, mineral admixtures, high strength aggregate and anti crack and wear-resistant agent. It is made by optimizing the formula design and production.
It has characteristics of high strength, high wear resistance, impact resistance, erosion resistance, anti-oil permeability, arbitrary shape control, strong integrity, simple construction, good construction performance, and long service . Because of the addition of high polymer, it is firmly bonded with the base concrete. High strength wear-resistant castable is the first choice for construction parts with wear-resistant requirements.
High-strength wear-resistant castable is specially used for the lining wear-resistant layer of slag sluice, ore trough, coal spout, hopper and silo in metallurgy, coal, thermal power, chemical, cement and other industries, and the blast furnace mixing silo, sintering silo, feeder, pelletizer, etc. In the iron and steel industry to protect the foundation concrete (or steel silo).
