Özet
Making concrete in the usual way produces a lot of carbon dioxide, so we need new ways to make building materials that are better for the environment. This study investigates the feasibility of producing one-part geopolymer foam concrete (GFC), utilizing Class F fly ash partially replaced by waste concrete powder (WCP) and reinforced with polypropylene (PP) fibers. Twelve mixes were prepared with 0–50 % WCP (by fly-ash mass) and 0–0.9 % PP fibers (by volume). The effects of these variations on fresh state properties, mechanical strength, density, thermal conductivity, porosity, chemical durability (against acid and sulfate attack), freeze-thaw resistance, and thermal durability were systematically evaluated. Replacing 25 % of fly ash with WCP maximized 28-day compressive strength at 5.97 MPa, an 80 % improvement over the control mix. Durability peaked when WCP and fibers were combined: the 10 …
