| Özet |
| This study develops alkali-activated slag composites incorporating WSP, 0-100 wt% as aggregate replacement and polypropylene fiber (PPF, 0-1.5 vol%) for ductility enhancement, targeting sustainable construction materials with reduced carbon footprint. Tests included; flow diameter, compressive/flexural strength, oven-dry density, water absorption, apparent porosity, sorptivity, elevated temperature (250-750 °C), freeze-thaw cycling (150 cycles), sulfate (Na 2 SO 4 ) and acid (H 2 SO 4 ) exposure, with SEM microstructural analysis. Mechanical characterization revealed that 100% WSP replacement achieved 29.29 MPa compressive strength at 28 days, representing a 108% increase over the WSP free control, attributed to optimized particle packing density and enhanced interfacial bonding. PPF incorporation increased flexural strength by 20-40% and energy absorption capacity by 3-8 times through crack … |
