MATERIALS AND MODERN STRUCTURAL SOLUTIONS FOR BUILDING STRUCTURES
https://doi.org/10.21822/2073-6185-2019-46-4-167-175
Abstract
Objectives. The aim of the work is to demonstrate the fundamental difference between fibre-reinforced foam concrete and traditionally-used wall materials in terms of tensile strength.
Method. An analysis of the effectiveness of heat-insulating and structural fibre-reinforced concrete in terms of their mechanical and physical properties, including frost resistance, is carried out.
Results. The characteristics of the most important operational properties of fibre-reinforced foam concrete for insulating and structural purposes are given. The possibility of expanding the range of prefabricated products in connection with the level of tensile strength of fibre-reinforced foam concrete under bending is substantiated. Empirical data concerning the practical use of original products from fibrereinforced foam concrete in the construction of residential and public buildings in Rostov-on-Don is presented.
Conclusion. It is shown that, in order to increase the heat transfer resistance of building envelopes, the use of fibre-reinforced foam concrete in the rehabilitation of existing buildings can ensure their high fire safety subject to the required sanitary and hygienic conditions. Fibre-reinforced foam concrete, being a gas-filled concrete of non-autoclave hardening, allows new design solutions to be offered for heat-insulating and structural purposes in the construction complex of the Russian Federation, which practical application expands the range of factory-made products, reduces energy consumption and contributes to the diversity of the architectural appearance of buildings.
