Geopolymer concrete (GPC) is increasingly seen as a sustainable alternative to Portland cement due its lower carbon footprint and improved durability. This study examines the effects of incorporating silica fume (SF) alccofine (AF) partial replacements (5%, 10%, 15%) for ground granulated blast furnace slag (GGBS) on mechanical properties GPC. It also assesses influence curing temperatures (27°C, 50°C, 80°C, 120°C) strength development. Results indicate that SF enhances compressive (CS), split tensile (STS), flexural (FS) at 5% replacement level, with maximum improvements 80°C. However, higher levels reduce strength. AF consistently boosts strength, highest gains 15% Response surface methodology (RSM) shows optimal content 5.606% 72.35°C, while achieves peak performance These findings offer valuable insights optimizing GPC mix designs improving under varying conditions.
