This study examines the effect of adding different dosages of nontitanium (NT) and nano-silica (NS) ranging from 0.5 to 4% by weight of binder materials on ultra-high-performance geopolymer concrete (UHPGC). The material’s feasibility was evaluated using slump flow measurements. A detailed analysis of its compressive strength (CS), transport properties, and sulfate attack was conducted. The addition of 2.5% NS and 4% NT improved the CS and transport properties of UHPGC compositions, creating a denser and more durable microstructure with enhanced interfacial bonding, as confirmed by the microstructure study. According to this study, the most effective doses for enhancing UHPGC performance in various aspects are 2.5% NS and 4% NT. The CS was recorded at 198.7 MPa for 2.5% NS mixes and 197.6 MPa for 4% NT mixes for ages test 28 days. These findings provide valuable insights into developing and utilizing advanced, high-efficiency UHPGC for sustainable and sturdy construction techniques. |
