AP25794279 – Fly ash - containing modified fine- grained concrete
Objective of the project – The project aims to improve the performance of fine-grained concrete by modifying its structure with a complex additive of fly ash and active components. The study will evaluate how this modification affects strength, frost resistance, and durability under aggressive conditions, while also assessing the practical effectiveness of fly-ash in construction.
Relevance: The relevance of the project is обусловлена the rapid development of the construction industry in Kazakhstan and the growing demand for fine-grained concrete. At the same time, the accumulation of ash and slag waste from thermal power plants creates environmental challenges. Their use in concrete mixtures helps reduce cement consumption and environmental impact. The development of fly ash-modified concrete improves strength and durability. Therefore, the study is both scientifically and practically significant.

Expected and achieved results: The project is expected to develop optimal compositions of fly ash-modified fine-grained concrete with improved strength, durability, and resistance to aggressive environments. It is planned to publish at least two articles in international peer-reviewed journals indexed in Web of Science or Scopus and to submit a patent application. As a result of the research, 25 compositions of fine-grained concrete based on fly ash from Almaty CHPP have been developed. Activated fly ash has been proven to improve the strength and rheological properties of concrete, with the optimal content determined at 5%. The chemical and mineral composition of the ash was analyzed, confirming the effectiveness of mechanical activation. The developed compositions are recommended for practical use in construction.
