    This research looks on the effectiveness of using nano-mineral admixtures in place of some cement for making self-compacting concrete (SCC). The goal is to improve concrete’s mechanical qualities while resolving the environmental issues raised by the manufacture of cement. Using an experimental approach, the study looks at several percentages (0%, 2.5%, 5%, and 30%) of nano-sized materials as partial replacements for regular Portland cement, including fly ash, silica fume, phospho-gypsum, and alccofine. Slump flow, J-ring, and L-box tests are used to evaluate the concrete’s fresh properties, including flowability, passing ability, and separator resistance. Evaluation of the toughened properties by tensile, flexural, and compressive strength tests provides insight into the achieved performance gains. Additionally, durability properties such as RCPT, water absorption and alkaline test were examined in terms of durability. The results point to the potential of nano minerals as sustainable alternatives in concrete by indicating a considerable improvement in the mechanical characteristics and durability of concrete with adequate nano mineral additive content. By giving a thorough analysis of nano mineral admixtures in SCC, this study advances the field and provides insightful information for the researchers to find the optimum replacement.
