Vibro-Cast Refractories Based on Silicon Carbide

To reduce porosity and enhance the density of vibro-cast materials, a study was conducted to evaluate the effects of a polycarboxylic acid-based superplasticizer, Kratasol PK, produced by JSC “Pigment.” Compatibility assessments were performed using high-alumina cement and KR-0 silica. The results demonstrated a significant reduction in water demand for the molding mixture, enabling the production of materials with increased density and reduced porosity. The use of this deflocculant resulted in a decrease in the water requirement of the molded mass to 5.7%.
