Hohe Festigkeit abriebfeste Feuerfeste Castab

High strength Abrasion-Resistant Refractory Castable is made up high strength aggravates and powder mineral additive.Through optimizing formula design, It has many excellent properties such as good brasion-resistant,high streghth, arbitrary shape can be controlled, strong property of integration , easy installation and good workability and so on. Since joining polymers, concrete bonded firmly to the grassroots.
