Castable Cement (LC Castable) is a low-cement-bonded refractory castable with high strength, high temperature resistance, low porosity, and excellent thermal shock stability. It is easy to install, can be cast to size according to site requirements, and is suitable for refractory linings of various high-temperature industrial equipment.

Castable Cement (LC Castable) is a type of high-grade refractory castable with a low-cement system. By optimizing the formula to reduce CaO content, the material forms a denser and stronger skeletal structure after high-temperature firing. Its characteristics include: higher compressive strength, excellent abrasion resistance, low porosity, outstanding thermal shock resistance, and better slag resistance and erosion resistance.
This material can be applied using vibration molding or self-flowing methods, exhibiting good workability and plasticity. After heating and drying, it forms a high-strength refractory layer, suitable for high-temperature industrial environments with high requirements for refractory performance and service life. LC castables are widely used in industries such as steel, building materials, non-ferrous metals, chemicals, and power, and are the preferred refractory solution to replace traditional high-cement castables and refractory bricks.
