Abstract:

Background: Experimental data on the conditions for the formation of gravel materials containing hollow aluminosilicate microspheres with a possibility to receive optimum structure and properties depending on humidity with the use of various binders are presented in this article. This article focuses on the scientific study of the possibility to optimize the physical and mechanical properties of composite materials.

Objective: The main goal of this research is an exploration of energy-efficient building materials to be used to replace natural materials with industrial wastes and development of the theory and practice of how to obtain light and ultra-light gravel materials based on mineral binders and waste dump ash and slag mixtures of hydraulic removal. The objective of this research is to study the composite material containing hollow aluminosilicate microspheres.

Methods: The study is based on the application of the separation method for power and heat engineering functions. The method is based on the use of the structure optimality factor that takes the primary and secondary stress fields of the structural gravel material into account. It shows the possibility to obtain gravel material with the most uniform distribution of nano - and microparticles in the gravel material and to form stable matrices with minimization of stress concentrations. Experiments show that the thickness of the cement shell that performs power functions is directly related to the size of the raw granules. At the same time, the cement crust thickness regardless of the binder type has a higher formation rate for larger diameter granules when the moisture content increases.

Results: The conditions of formation for gravel composite materials containing hollow aluminosilicate microspheres were studied. The optimal structure and properties of the gravel composite material were obtained. The dependence of the strength function on humidity and the binder type was investigated. The optimal size and shape of gravel material containing aluminosilicate hollow microspheres with a minimum thickness of a cement shell and a maximum strength function were obtained.

Conclusion: The obtained structure enables us to separate power and heat engineering functions in the material and to minimize the content of the aggressive environment centers.
