The peculiarities of the deformation diagram under short-term central axial compression of concrete of the frame structure of class B60, obtained by immersing a large aggregate in a low-viscosity solution component, are revealed. The boundaries of microcrack formation of concrete are determined. A good correspondence of the main regularities of the change in the tensile strength and deformation properties of a concrete frame structure with some known data is shown. The possibility of an analytical description of the deformation diagram of a concrete frame structure known formula Sargine (Sargine) is confirmed. Data are presented on the change in the initial modulus of elasticity, the Poisson's ratio, the change in the volume of concrete and the propagation velocity of ultrasound in concrete, depending on the level of loading. The ratio of cubical and prismatic strength is given. The conclusion is made about the expediency of using concrete frame structure in reinforced concrete columns.

Keywords: concrete frame structure, tensile strength, modulus of elasticity, deformation diagram, parametric points, microcrack formation, superplasticizing additive

Building activity is one of the main anthropogenic factors of environmental impact. Obligatory project appraisal is conducted concerning all presented sections, including “Environment protection checklist” that is meant for the initial stage of object exploitation. The obtained values meet all environment protection requirements, and they change both for better or worse in the period of exploitation. In order to provide stable values of environmental protection, environmental monitoring should be performed. It should contribute to the development and organization of surveillance system, environmental assessment and state-of-the-environment-forecast that should provide support of environment in the satisfactory condition. In the process of organization of territorial-manufacturing, residential, and civil complexes, development of industry and building, urban redevelopment, etc., maximum permissible loads (MPL), acceptable from the environmental point of view, should be determined. At the same time nature resource management should correspond to the ecological “tolerance” (capacity) of the territory.
