The comparison of silicate binder refractory concretes with alumina binder concretes

Nowadays refractory products and materials are used widely in different industries, plants and furnaces. Refractory concrete is one of the refractory products which is considered as an unzinpered refractory product. Refractory concretes can be categorized by different parameters. Silicate binder and alumina binder refractory concretes are two kind of refractory concretes which are the subject of this research. Various researches, tests and analysis of variation of refractory characteristics with increasing the temperature show that with respect to silicate binder concrete, alumina binder concrete shows better physical and chemical properties and better refractory specifications in high temperatures and so is used more in manufacturing the refractory products.
