ESTIMATION OF THE MAXIMUM TEMPERATURE REACHED DURING THE HARDENING OF CONCRETE

Abstract

In the conditions of growing environmental problems and increasing energy consumption, the development of new technologies for manufacturing building structures is an important task of the construction industry. One of the key factors that affects the quality and duration of use of building materials is heat treatment of concrete. This process has a positive effect on a number of material parameters, such as strength, frost resistance, waterproofing and durability. However, in conditions of excessive electricity consumption, the need to reduce energy costs in the production process becomes urgent. Accordingly, the development of new technologies should include strategies to reduce energy consumption and optimize technological cycles. In Ukraine, as in other countries, the issue of rational use of energy is of great importance. Taking into account the peculiarities of the country's energy sector, an important direction is the use of alternative energy sources. This opens the way to the development of sustainable and efficient construction that takes into account the environmental and energy requirements of the present. In search of optimal ways to improve the properties of concrete, which determine its reliability and durability, scientists pay attention to the complex influence of various factors. In particular, vibration, excess pressure, temperature regimes and chemical additives play a key role in improving the quality characteristics of concrete. These methods make it possible not only to significantly improve its strength, but also to provide excellent strength of conventional materials, improve resistance to wear and aggressive environments. In modern conditions, when competition in the field of concrete products production is high, it is important to find a balance between achieving high technical characteristics of the material and maintaining economic feasibility. The use of high-quality fillers and high-quality binders increases the strength of concrete, but this can lead to an increase in the cost of the product and a decrease in its competitiveness. Unfortunately, one of the urgent problems is the decrease in production of high-quality raw materials for the construction industry. Many deposits have been exploited or exhausted, which jeopardizes the stable supply of high-quality binders and aggregates. In light of these challenges, it is extremely important to look for internal reserves to increase the strength of concrete. The use of local building materials and optimization of processes can be the answer to these problems. The application of innovative production methods and the use of alternative energy sources can contribute to the sustainable and ecologically balanced development of the construction industry, saving resources and reducing the negative impact on the environment.
