Resumo

Highly porous materials are the basis for four product groups: heat insulation, sound insulation and sound absorption, as well as insulation filling. In all cases, the parameter determining the properties of these materials is porosity, which also determines the conditions for energy transfer in the material. Pore size and shape, pore size distribution and porosity, thickness, structure, and nature of inter-ring membranes are also important characteristics (determining, first and foremost, their strength. These features of the structure and their influence on the properties of materials can be considered in the implementation of structural and mathematical models. The article describes the method and results of construction of complex structural model of high porous products on the example of particularly light and heat insulating mesh concrete. Analytical expressions for compressive strength, medium density and thermal conductivity are obtained. A nomogram has been constructed, with the help of which prognostic tasks of assessment of properties of mineral products of honeycomb structure can be solved depending on their porosity and nature of the structure-forming component.
