Ltd., Luoyang 471039, China ABSTRACT W ith the castable rheometer, Lbox flowability test apparatus and selfflow test apparatus, the influence ofwater addi tion, dispersant content ( FS10), aluminate cement content and AlO content on the rheology and flowability of a corundumbased 2 3 selfflow castablewere researched, and the relationship bewt een rheological properties and flowability of the castable were analyzed. The results show thatw ith the increase ofwateraddition ( 49% to53%, mass fraction), the relativeyield stress, relative plasticvis cosity and relative average viscosity decrease, but the selfflow value and flow velocity increase. W ith the increase of dispersant FS10 ( 016% to020%, mass fraction), the relative yield stress, relativeplastic viscosity and relative average viscosity decrease, but the
