Wear-resistant castables
Classification:
Product Introduction
This series of high-strength wear-resistant castables are made of high-quality high-aluminum chamotte as aggregate, and are developed by introducing ultrafine powder and high-efficiency water reducing agent. The products have the characteristics of good construction performance, high bonding strength, wear resistance, and good volume stability.
