Özet
The utilization of natural clinoptilolite zeolite (CZ) as a precursor in geopolymers represents a promising approach to enhancing both the performance and sustainability of alkali-activated composites. This study investigates the development of sustainable alkali-activated foam concrete (AAFC) by employing 100 % pumice aggregate as a lightweight aggregate and partially replacing ground blast furnace slag (GBFS) with fly ash (FA) and CZ. The objective is to assess the combined effects of FA and CZ on the mechanical, thermal, and durability properties of AAFC under varying curing conditions, including exposure to extreme temperatures and freeze-thaw cycles. The results indicate that flowability of the fresh mixtures increased with the incorporation of FA and CZ. Compressive strengths ranging between 2 and 5 MPa were achieved over a curing period of 7–120 days with unit weights below 723 kg/m³ …
