ALUMINA CEMENT, ALUMINA CEMENT COMPOSITION AND MONOLITHIC REFRACTORY

摘要

PROBLEM TO BE SOLVED: To provide alumina cement capable of keeping the fluidity for a long time at a low temperature and having high strength and an alumina cement composition and monolithic refractory using the same.

SOLUTION: The alumina cement containing CA and C2AS as a mineral composition contains 25-40 mass% CaO and 0.01-0.15 mass% potassium expressed in terms of K2O. The alumina cement composition contains the alumina cement and aggregate. The monolithic refractory contains the alumina cement and refractory aggregate.
