Özet
The incorporation of activated carbon (AC) into construction materials offers a sustainable pathway for valorizing agricultural waste, enhancing certain performance aspects, and reducing the environmental footprint of cementitious systems. In this study, the effects of coconut-shell-derived AC and hybrid fiber reinforcement on the mechanical and durability properties of one-part alkali-activated slag composites (AACs) were evaluated. Sixteen mixtures were produced by replacing ground granulated blast-furnace slag (GBFS) with AC at 0 %, 7.5 %, and 15 % by mass, and adding 2 vol% total fibers as glass fiber (GF), polypropylene fiber (PPF), or hybrids. Increasing AC content consistently reduced flowability (up to −11.8 % at 15 % AC) and oven-dry density (from 2226 kg/m³ in reference to 1985 kg/m³ at 15 % AC + 2 % PPF) while increasing porosity (from 3.66 % to 13.09 %) and water absorption (from 2 …
