| چکیده | ||
| As Portland cement production greatly affects the environment, more focus is being placed on using geopolymer concrete (GPC) as an alternative. This study explores the mechanical performance of high-performance fiber-reinforced geopolymer concrete (HPFRGC) using slag-based binders partially replaced with silica fume at levels of 0%, 5%, 10%, and 15%. The effects of incorporating steel and glass fibers at 0.5% and 1% volume fractions on compressive and splitting tensile strengths were also evaluated at 7 and 28 days. Results indicate that 5–10% silica fume replacement enhances compressive and tensile strength, with 10% being optimal. Excessive replacement (15%) reduced strength due to dilution of reactive content. Steel fibers were more effective than glass fibers, particularly at 1% content, yielding up to 12.7% and 38.6% improvements in compressive and tensile strengths, respectively. Moderate benefits were seen from using glass fibers, mainly in tensile performance. Failure pattern analysis showed that fiber-free specimens experienced brittle fractures, while fiber-reinforced mixes exhibited improved crack control and ductility. Overall, the combined use of 10% silica fume and 1% steel fiber offers the best enhancement in mechanical performance, suggesting an effective approach for developing sustainable, high-performance geopolymer concretes. | ||
