Processes associated with obtaining various purposes silicate materials is always accompanied by energy exchange between the interacting phases. Their thermodynamic analysis is not always possible due to the lack of appropriate reference material.
This paper proposes a priori estimate of the thermodynamic functions of silicate formation, as well as other oxide minerals, and their crystalline hydrates.
Keywords: silicates, thermodynamics, functions, education, specific heat.

Statement of the problem. Preparation of high-strength foam concrete in construction allows for energy and resource conservation. Water covers more than 50% of their dense component and on its properties depend strongly on structural properties of foam concrete, is not fully explored.
Results. The effect of mixing water of low temperature on the structure and properties of constructive penofibrobetonov. Recommendations on the account in the calculation of reinforced concrete elements elevated structural properties and deformation diagrams penofibrobetonov by mixing water setback.
Conclusions. Using low temperature mixing water improves the structure, increases the strength, deformability and elastic modulus, as well as changes of the deformation diagram fibropenobetonov.
Keywords: fibropenobetona, foam, water temperature mixing, macroporosity, economic efficiency, technical and economic assessment.
