The Influence of Rheology for Different Superplasticizer on High Alumina Low Cement Castable

Fixed the composition of matrix slurry in low cement castable, added different additives such as STPP, KS-JS70, GLENIUX, Rheoplus, LMS-P, determined the slurry viscosity by using the NXS-11A rotary viscometer, analysised the rheological properties of the different matrix paste.Studies have shown that: there is a certain influence on the slurry rheology for different species and dosage, and there is the appropriate dosage. Analyzed the mechanisms of different admixtures on the rheological properties of slurry on theoretical.
