Mechanical Properties of Cement-Free Bauxite Based
Cement-free castables bonded by hydratable alumina with or without SiO2 fine powder were prepared with bauxite as main raw materials. The mechanism of castables mechanical performance as sintering temperature increased was investigated. The results showed that the strength of these castables decreased at relatively low temperature because of the hydrates de-watering and the transforming
