“…Задачи создания новых материалов, отвечающих требованиям времени, развитие технологий, выходящих за рамки решения типовых практических задач строительной отрасли, и, соответственно, возникновение сопутствующих проблем составляют картину современности [3,4,5]. Своевременный расчет надежности конструкций позволяет избежать негативных последствий и техногенных аварий на производстве, что остаётся одной из важнейших задач в современном строительстве [6,7].…”

the requirements of modern construction are the strength of building structures, as well as low cost. It is these conditions that provide new technologies that are constantly being improved. The article is devoted to the consideration of cases of a probabilistic approach to solving the problem of theoretical energy consumption for the destruction of concrete of ideal structure. The processes of concrete deformation and its destruction are studied by building mechanics. Concrete is a multicomponent material, which presents a certain difficulty in the study of crack formation. In operating conditions, the concrete/reinforced concrete structure is affected by the properties of its constituent materials; therefore, one of the most important tasks is the selection of criteria that can comprehensively characterize the basic parameters of concrete. Obtaining the strength characteristics of concrete of operated structures remains an urgent task. The article proposes to consider the ideal structure of concrete. The features of this structure are the symmetry of fracture along two principal planes. The destruction of concrete was carried out by sawing individual strips of concrete. Moreover, to describe the sawing process, the authors proposed a model of a symmetric structure of concrete in which aggregate grains are idealized. They are presented in the form of balls in the body of concrete. The features of the sawing process are revealed. The analytical dependencies of fracture sawing the ideal structure of concrete are obtained. Conclusions are drawn about the possibility of using the ideal model for obtaining the strength characteristics of concrete. The analysis of symmetrical ideal concrete compositions with various variables is performed. The significance of the work done lies in the possibility of transferring the research results to real buildings and structures and solving the main tasks that are posed in the study

Nuclear power has important fundamental features that are absent in other power generation technologies, since nuclear fuel has million times larger energy content, while nuclear waste is relatively low in volume, which makes it reliably localizable. This paper presents a study of the strength and electrical insulation properties of polymer concretes in a wide range of altering the polymer-concrete ratios. The analysis has identified an optimal polymer-cement composition for electrical insulation. It is herein demonstrated that polymer cements can be used for insulation of electromagnets. The tasks of creating new materials that meet the requirements of the time, the development of technologies that go beyond the solution of standard practical problems of the construction industry, and, accordingly, the emergence of related problems are the picture of modernity. This paper is useful for further developments in the construction industry, designed to solve the problems of using modern technologies and materials that have a negative impact on the environment. Thus, this allows the application of this approach in complex construction situations, including when working in environmentally complex areas, for leveling radiation.
