Low Cement Castable
LCC&ULCC refractory castable have the characteristics of small porosity, high density, good volume stability, high strength and small water addition. At the same time, LCC&ULCC overcomes the characteristics of the common castable that the strength of the castable decreases significantly at 800~1200℃, strength of LCC&ULCC increases with the increase of temperature. What is more, it has excellent thermal shock resistance, slag resistance and corrosion resistance.
Low Cement Refractory Castable Characteristics:
High temperature resistance 1800 degrees
High intensity
Excellent thermal shock resistance
Good corrosion resistance
Easy use when construction
