WebApr 11, 2024 · Therefore, a research project was undertaken to develop high-performance concrete (HPC) using available supplementary and waste materials, such as fly ash (FA), silica fume (SF), Quartz filler (QF), and limestone powder (LSP), as partial replacements for cement in binary and ternary blends under various curing conditions. WebThe experimental program was designed to investigate fly ash as partial cement replacement in concrete. The replacement level of the cement by fly ash are selected as 15%, 30%, 45%, 60% and 75% for standard size of cubes for the C30 grade of concrete. The specimens of standard cubes (150 x 150 x 150mm), was casted with fly ash.
