The influence of the deflocculant of the Russian company Polyplast-UralSib LLC on the properties of trough and self-flowing masses for lining the working surfaces of thermal units is considered. It is established that introduction of a deflocculant in an amount of 2.0 wt.% into refractory concrete masses ensures satisfactory workability of the mass and the required physical and mechanical properties of concrete after firing at 1000 and 1400°C, compared to the introduction of imported deflocculants ADW/ADS and SioxX/Siox-Quick. It is shown that the trough concrete obtained using the Russian deflocculant has higher strength than concrete with an imported deflocculant, including 0.5 wt.% ADW1 and 0.5 wt.% ADS3. Petrographic analysis revealed equal resistance of the trough concrete to the effects of blast furnace slag whether the Russian additive and or the imported SioxX and Siox-Quick additives were used as deflocculants in the amount of 2.0 and 0.5 wt.%, respectively.
