Abstract

The article describes how, using a penetration viscometer and a specially developed technique, the limiting shear stress and viscosity were measured in compacted solid three-phase dispersed systems: hammer-moistened sand of various dispersities, mixtures of ground and Volsky sand of natural dispersion and cement-sand mixtures. It is noted that the obtained dependences of rheological characteristics on humidity, specific surface area and porosity show a direct relationship between the rheological properties of three-phase dispersed systems with capillary coupling. This makes it possible to effectively influence the amount of capillary adhesion and the associated rheological properties of dispersed systems used for the production of building materials.
