High Quality and Performance Low Cement Refractory Castable
Product Description
The cement content of the traditional common refractory castable is as high as 10 ~ 30%, while the matrix of low cement and ultra-low cement is prepared by replacing part or most of the cement with ultra-fine powder (particle size less than 5um) with a small amount of dispersant (water reducer) and a certain amount of delayed retarder.
