Guidelines on calculation of the concrete thermal treatment modes

Abstract

Abstract.The article provides guidelines on calculation of the cast-inplace reinforced concrete thermal treatment modes: the problem of thermal treatment mode by setting the mathematical temperature field model in the hardening concrete has been solved; model equation which allows calculating the temperature field in the hardening concrete structure using computer software has been solved. These data allow to achieve the high quality of concrete at minimum heat treatment duration and the maximum reduction of energy costs, while minimizing experimental calculations. The energy efficiency problem of economy class residential buildingsOne of the most pressing social problems in the world is the problem of housing for citizens, towards whom the state has obligations in accordance with applicable law. Currently, the most efficient way to solve this problem directly is a mechanism of provision of housing at the expense of state funds. Successful completion of such programs is also achieved due to the formation of an affordable economy class housing market that meets the requirements of energy efficiency and environmental friendliness. In turn, the energy efficiency criterion is achieved by rational choice of technology and organization of construction operations [1, 2]. Energy efficient concrete temperature conditionsCurrently, the use of technology and organization of construction by cast-in-place method, which has a significantly accelerated level of adoption, has been increasingly recognized in the construction industry. An important criterion for energy efficiency of cast reinforced concrete technology utilization is the rational temperature condition of concrete hardening [3]. It is necessary to have a common method of the temperature field calculation in the hardening concrete structure for a satisfactory resolution of this problem. The implementation of this calculation method by using computer modelling is currently possible and relevant due to the widespread use of computer technology [4,5].

Anthropotechnical technologies for monitoring engineering systems

“…Ensuring a comprehensive life safety through a variety of functional subsystems, which have a set of characteristics of the elements of quality systems identified when considering it from the standpoint of each of the varieties of construction reorganization, will provide the ability to simulate the main criteria for assessing the efficiency of the monitoring system for managing the quality of engineering systems of buildings and structures. The quality of construction products is influenced by the stability of technological processes, compliance with the correct technological sequence of work performance, coordinated actions of all departments of a construction organization and its subcontractors, rhythm of production, timely completeness, and a high degree of prefabrication of structures [1][2][3][4][5][6][7][8][9][11][12][13][14][15][16][17][18][19]20].…”

The method of using current regulations and standards in designing management and technologies of construction

“…"Analysis" allows monitoring the use of human, technical and material resources. Also, this section includes a part of financial policy, thus clearly shows the costs and revenue of a company from using each of the methods of construction and installation works [5,6].…”

Analyzing the functional capabilities of modern systems, methods and means for scheduling

“…Investment and construction project is a complex system shifting from one stage to another one in the course of its whole life cycle. Such stages are referred to as the project phases, and each of them has its specific features and risks, so projecting methods for scheduling at various stages shall be different [3,4].…”
