The Differences in Performance between Lightweight and Heavy Alkali-Resistant Castables

Castable refractory materials that can resist the corrosion of alkali metal oxides (such as K2O and Na2O) at medium and high temperatures are called alkali-resistant refractory castables. The composition of this type of castable is similar to the castable combined with ordinary calcium aluminate cement. It is a mixture composed of alkali-resistant refractory aggregates and powders, binders, and additives. Rongsheng refractory manufacturers will start with the classification of alkali-resistant refractory castables and show you the differences in performance between lightweight and heavy alkali-resistant castables.
