Abstract
The influence of the deflocculant of the Russian company Polyplast-UralSib LLC on the properties of the groove and selfdissolving masses for lining the working surfaces of thermal units is considered. It was found that when a deflocculant is introduced into the refractory concrete masses in an amount of 2.0 wt. % satisfactory workability of the mass and the required physical and mechanical properties of concrete after firing at 1000 and 1400 °C are ensured compared to the introduction of imported deflocculants ADW / ADS and SioxX / Siox-Quick. It is shown that the gutter 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 trench concrete to the effects of blast furnace slag when using Russian additives and imported SioxX and Siox-Quick in the amount of 2,0 and 0,5 wt. % as deflocculants respectively.
