Innovative development of high-strength concrete with ultrafine metakaolin-heated POFA binders and fine coal bottom ash aggregate: Strength, durability and microstructural performance

Abstract The production of high-strength concrete (HSC) remains heavily dependent on cement and natural sand, despite the urgent need to reduce the carbon footprint of construction materials. Meanwhile, substantial quantities of palm oil fuel ash (POFA) and coal bottom ash (CBA) remain underutilized...
