Abstract
The study aimed to produce SCC by mixing fly ash and silica fume, two typical mineral wastes. Two binary blended mixes were created: the first replaced cement with fly ash in varying percentages (10%, 20%, 30%, and 40%), while the second took the best fly ash mix and replaced cement with silica fume at 5%, 7.5%, and 10%. Important studies that were carried out included tests for workability, compressive strength, split tensile strength, water sorptivity, and rapid chloride penetration. Compared to regular concrete, the performance attributes improved as these components were added to SCC.
