Özet
This study evaluated the effectiveness of using vegetable waste ash (VA) and fly ash (FA) as sustainable partial replacements for ground blast furnace slag (GBFS) in alkali-activated foam concrete (AAFC) to improve mechanical properties, thermal insulation, and durability. VA, sourced from incinerated vegetable processing waste, and FA were used both individually and in combination to replace GBFS at 5%, 10%, and 15% by weight. The AAFC mixtures were prepared with a fixed binder content of 500 kg/m3 and a water-to-binder ratio of 0.45, using pumice as the lightweight aggregate. The mechanical, fresh, and durability properties of AAFC mixtures were evaluated using sodium metasilicate as an activator, with curing at 80°C for 24 hours followed by ambient exposure. Compressive and flexural strengths were tested at 7, 28, and 91 days. Results indicated that VA significantly enhanced compressive and …
