Rheological and mechanical properties of aluminosilicious cementitious materials as refractory castable binders
文献摘要：
Metakaolin(MK)is an important refractory raw material,which has been used as a cementitious material.In order to improve the bonding strength of MK,the composite cementitious materials were prepared by MK mixed with hydrat-able alumina(HA)and microsilica(MS),respectively.The silane coupling agent(SCA)was introduced as a modifying agent.The rheological properties of MK-based composite cementitious slurries were investigated.The mechanical properties of corundum castables bonded with the composite cementitious materials and calcium aluminate cement(CAC)were comparatively studied.The results show that SCA improves the rheological properties of MK-based composite cementitious materials.The slurry of MK-MS mixture flows in a plastic manner,while the slurry of MK-HA mixture presents pseudoplastic flow.The addition of SCA reduces the yield stress value of the MK-HA slurry.The bonding strength of castables bonded with MK-based composite cementitious materials is lower than that of CAC bonding castables.The room temperature strength of MK-MS composite bonding castable remains the highest after being treated either at 1100 or 1550℃,and its high temperature modulus of rupture is higher than that of CAC bonding castables with microsilica added.
