Low cement (LC) castables are refractory materials that contain a reduced amount of cement compared to traditional castables. By reducing the amount of cement, the water demand of the castable is lowered, resulting in shorter installation time. These materials are characterized by their low porosity, Optimum Hot strength, chemically stable, High density & load bearing capacity. They possess excellent resistance to thermal shock and abrasion . They are commonly used in DRI Kiln lining, Inlet cone, cooler section & Burner pipe of Cement Rotary Kiln, Incinerator lining, steel laddle , tundish & aluminium Industry.
