This study investigated the impact of sulfate-resistant mineral admixture (SP2) and untreated sugarcane bagasse ash (SCBA) as a partial substitute for cement on physico-mechanical properties microstructure Portland concrete. Four concrete mixtures were prepared investigation including control mixture, SP2 mixture (4.7% SP2), SCBA (5% SCBA), SP2-SCBA 5% SCBA). The exhibited superior performance across all assessed engineering in comparison to other mixtures. Moreover, comparative analysis was conducted evaluate used this versus processed from recent research. Remarkably, SCBA, despite having minimal compressive strength, it demonstrated notable improvements tensile strength. When combined with 4.7% SP2, achieved remarkable 37.9% increase splitting strength compared outperforming similar using silica fume previous studies. Microstructure revealed large amount spongy, fibrous hydrated structures both These provide rational explanation containing SCBA. findings highlight tradeoff between treated sustainable replacements. Although can only be at low replacement level, offers unique benefits alongside significant energy savings.
