內(nèi)容簡介Microsilica-gel bonded bauxite based no-cement refractory castables(NCCs)have been produced using two readily available dispersants.These NCCs were compared to NCC with Siox X-Zero,a purposely-developed product for microsilica-gel bonded no-cement castable systems to control flow properties and setting characteristics.Three mixing and curing temperatures were applied:5℃,20℃and 35℃.The results show that setting-behaviour and mechanical properties strongly vary with the type of dispersant and the curing temperature.However,both setting and strength are less temperature dependent in the castables with Siox X-Zero.Furthermore,the drying and firing of microsilica-gel bonded NCCs were investigated.Since microsilica-gel bond system contains only a small amount of bound water,the castables can be fired at very high heating rates,once the free water has been removed.
