Abstract
The article presents the results of using information technologies in the study of changes of concrete characteristics at different hardening conditions. The use of the developed temperature measurement complexes made it possible to control the conditions of hardening of monolithic concrete structures directly under production conditions. The results by means of using regression analysis are obtained, regression models of the dependence of the compressive strength of concrete on time and hardening temperature are determined. A significant decrease in compressive strength and resistance to air penetration of concrete samples during their storage under conditions of significant temperature fluctuations has been established.
Highlights
The development of new materials, the introduction of automated design systems and methods of work organization, make it possible to improve construction technology, but builders still have many problems
Analyzing the experience accumulated and conducted research in the field of production and quality control of concrete work, as well as the experience of winter concreting of construction organizations in our region, it can be noted that despite the large amount of information and a detailed description of methods of concrete care at low temperatures, there are a lot of abnormal situations [8]
This requires research to identify the causes that reduce the reliability of monolithic concrete structures
Summary
The development of new materials, the introduction of automated design systems and methods of work organization, make it possible to improve construction technology, but builders still have many problems. Analyzing the experience accumulated and conducted research in the field of production and quality control of concrete work, as well as the experience of winter concreting of construction organizations in our region, it can be noted that despite the large amount of information and a detailed description of methods of concrete care at low temperatures, there are a lot of abnormal situations [8] This requires research to identify the causes that reduce the reliability of monolithic concrete structures. As a result of researching various methods of heating concrete and hardening accelerators, the main factors (average monthly and minimum ambient air temperature; temperature of the concrete mixture being laid and its survivability; thermal resistance of the formwork and its area) were determined, reducing the reliability of monolithic structures [6] These factors significantly influenced the rate of structure formation and, required constant adjustment of the dosage of modifiers. The development of dependencies for predicting and controlling the concrete characteristics of various compositions and strength classes becomes very important
