Product Description
Low cement castable
is mainly used with the main material chemical composition of the same or similar ultramicro powder to replace most or all of the cement, refined, scientific use of optimization particle size, micro powder, particle shape and other factors,at the same time with the addition of micro dispersant (water reducer) and appropriate amount of retarder compound admixtures.
