The authors have analyzed types of cohesion between water and fillers that demonstrate
varied granulation. The authors have proven the influence of the moisture content in fillers onto their
packing density.
An experimental and theoretical analysis of influence of types of cohesion between the water
and surface particles of the liquid phase in the period of initial structurization of foam-concrete
composites represents an intermediate step on the way to identification of patterns of formation of
structures that have perfect physical and mechanical properties.
The experimental research consists in the moisture treatment of disperse granular particles
of sand and dense limestone of different fractions. The experimental research has proven that the
packed density of dry fillers depends on the size of elementary particles; therefore, the packed
density depends not only on the type of packing of particles, but also on correlations between their
gravitational and surface energy.
The amount of water consumed in the course of formation of adsorption films has turned out
to be proportionate to the per-unit surface of granular particles. The moment when the particle surface
was filled with the adsorption moisture was registered based on the minimal average density
in cases of the varied moisture content in the materials under research. Each granular composition
demonstrated higher parameters of average density upon formation of the adsorption layer of moisture
due to the presence of the film characterized by higher density.
The growth of average density in the absence of any water loss proves that the granular system
has a film moisture content that demonstrates the properties of a solid phase.
The findings have proven that the degree of dispersion of granular particles regulates the film
moisture content in the composites designated for the production of foam-concretes. The above
property ensures production of composites that have a high workability and a stable aggregative
state.
