Abstract
The effect of thinning agents on molding mixtures for the production of high-alumina ceramic castables composed of bauxite HCBS (highly concentrated ceramic binding suspensions) and a refractory filler based on fused corundum and SiC is studied. The thinners used were sodium tripolyphosphate (STPP), SB-5-grade organic plasticizer, mixtures thereof, and liquid glass. The maximum thinning effect is observed for complex organomineral additives (10 – 33% SB-5 + 67 – 90% STPP). The optimum thinner concentration is 0.08 – 0.1 wt.%. The use of thinners makes it possible to reduce significantly the water demand of concrete mixes and leads to a decrease in porosity and an increase in strength of ceramic castables. The composition and concentration of alkali-containing thinners produce little (if any) effect on the deformation behavior of ceramic castables at high temperatures.
