AP27511185 – Energy-saving technology for production of unstressed reinforced concrete products using fine-grained self-compacting concrete
Objective of the project – The objective of the project is to develop and test the composition of fine-grained self-compacting concrete of strength class B30, adapted for energy-saving vibration-free technology for the production of unstressed reinforced concrete products.
Relevance: The project “Energy-saving technology for production of unstressed reinforced concrete products using fine-grained self-compacting concrete” aims to develop and industrially test a B30 class fine-grained self-compacting concrete for vibration-free, energy-efficient production with reduced isothermal curing temperature without compromising product quality. The relevance of the project is driven by the widespread use of conventional vibration-compacted concrete in Kazakhstan and the need to improve working conditions by reducing noise and eliminating harmful vibrations in confined industrial environments. The project includes theoretical and applied research on mix optimization, analysis of Dr. Ozawa’s blocking criterion, and investigation of cement hydration temperature, including the possibility of reducing curing temperatures below 50°C. As a result, a technological regulation will be developed, ensuring improved labor conditions, reduced energy consumption, higher production efficiency, and strong potential for rapid industrial implementation and commercialization.

Expected and achieved results: As a result, it is planned for the first time to develop technological regulations for producing B30 class reinforced concrete products using vibration-free technology. The social effect lies in improved working conditions through reduced noise and vibration, as well as simplification of the production process. The economic benefit is achieved by lowering energy consumption due to reduced isothermal curing temperature and elimination of vibration compaction technologies, including costs for equipment purchase, maintenance, and operation. The results are applicable, commercially viable, and of interest to existing enterprises, as the technology can be implemented at current production facilities without significant process changes. The project will result in at least four publications in Web of Science and Scopus-indexed journals and one patent application for a utility model in Kazakhstan.
