Low&Ultra-low Cement Castable
Description

Description of Low&Ultra-low Cement Castable:

LCC&ULCC 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.
