Annotation

Over the last decade, the trend of producing monolithic concrete and reinforced concrete with increased strength indicators continues in Ukraine and the world. Ensuring the performance of concrete and short roads is one of the main tasks of the technology of reinforced concrete products in modern times.
It is known that thermoforce processing can have a positive effect on the properties of concrete - such as volume, strength, corrosion resistance, water permeability, durability. In these industrially developed countries, the use of concrete with increased physical and mechanical indicators is growing.
In the construction industry, there is a problem of saving money and energy security. The application of the thermoforce method for the production of new-generation concrete allows to increase the indicators of strength, corrosion resistance and other physical and mechanical properties of concrete.
In conditions of high competition in the production of concrete products, obtaining high-strength concrete by using high-quality aggregates and binders of high grades sharply increases the cost of the product and makes it uncompetitive. There is a problem related to the reduction in the production of high-quality binders and aggregates due to the extraction of quality raw materials. Most of the quarries, where quality raw materials for the construction industry were mined, are abandoned or exhausted. Therefore, it is necessary to identify internal reserves of concrete strength growth, to solve the acute problem of saving resources and energy saving, using ordinary components and local building materials. It is possible to significantly open the strength reserves of concrete and increase the physical and mechanical properties of concrete through the complex influence of such factors as vibration, excess pressure, temperature and chemical additives.

Keywords: concrete, strength, weather resistance, water permeability, durability, thermopower technology
