Evaluation of the influence of coal combustion products on the pozzolanic and hydration reactions of cement-based composites

This thesis explores the use of coal bottom ash (CBA), a by-product of coal-fired thermal power plants, as an alternative material in cement production. The open disposal of CBA causes environmental issues, while cement production generates enormous carbon dioxide emissions. This study processes CBA into a finer material that reacts effectively in cement mixtures. Laboratory tests confirm its ability to improve strength and reduce the release of harmful elements. The findings demonstrate compliance with international standards. This research offers practical solutions for recycling industrial waste, supporting decarbonisation, promoting the circular economy, and advancing sustainable cement production in the construction industry.
