RHEOLOGICAL PROPERTIES OF HIGHLY CONCENTRATED AQUEOUS DISPERSIONS BASED ON SILICATES AND ALUMINOSILICATES IN THE PRESENCE OF SUPERPLASTICIZER ADDITIVES

Results of the study of rheological properties of inorganic dispersion s of silicates and aluminosilicates in water in the presence and absen ce of added PSG [1 - 3] and S-3(1) anionic surfactants are presented. The results of experimental studies were analyzed using the Ree-Eyring flow theory. It was shown that the addition of PSG, which is a mixtur e of sodium salts of aromatic sulfonic acids of different structure [1 - 3], decreases the level of apparent viscosity and shear stress most efficiently, noticeably changing the structure and thixotropic proper ties of suspensions.
