Refractory Cement Overview

refractory cement is mainly made of calcium aluminate. It is a hydraulic binder that is designed to resist thermal and mechanical stresses, making it an excellent choice for environments that experience high temperatures, such as furnaces, kilns and other industrial applications.

Refractory cement is also called calcium alumina cement, heat resistant cement, monolithic refractory cement, moldable refractory cement, fireproof cement and so on. According to different using environment, you can choose suitable refectory cement for your project.
