Gelation in Three-Phase Disperse Systems

Abstract:

The work considers the pre-requisites for the development of a scientific methodology of determination of optimum water content in hard raw mixes used for the production of high-strength concrete. The main idea of the methodology is the capillary structures hypothesis which considers the laws of formation of irregular structures under the conditions of balance of the forces among the particles in three-phase disperse systems. The structure formation under the effects of capillary cohesion in disperse systems has been studied; the capillary cohesion was considered as a factor influencing the formation of the optimum structure of raw mixes for compressed construction composites and determining the strength of the products.
