Refractory Castable
INTRODUCTION
High aluminum castable is high aluminum aggregate with AL2O3 content greater than 75% as particle raw materials, combined with high aluminum powder and admixture composed of the overall aluminum content > 55% of the amorphous refractory castable, high aluminum castable after the initial solidification, standard curing to 28d, compressive strength up to 40~60MPa. It is characterized by slow hydration rate, high late strength and high refractoriness.
FEATURES
1. High refractoriness under load；
2. High compressive strength；
3. Good abrasive resistance ；
