Abstract
Traditionally, calcium aluminate cement is always used as the binding agent for refractory castable applied in steel and iron, but cement contains many impurities, it is easy to generate low-melting additives and excessive liquid phase may be formed in material calcination, so the thermal shock resistance and moderate temperature intensity of corundum castables bonded with cement is worse; in addition, the flowability of cement-bonded castables also is poorer and it is difficult to construction. In the recent years, China and other countries have started to study properties of colloidal sol bonded castables to improve physical/chemical properties and workability of cement castables. This paper summarizes some characteristics of silica sol bonded materials via test and analysis.
