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.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production. During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured. Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
