Özet
The development of sustainable and energy-efficient construction materials is crucial for reducing environmental impact and improving building performance. This study investigates the effects of slaked lime (LM) and mahogany sawdust (MS) as partial replacements for fly ash (FA) and silica sand (SS) in one-part geopolymer foam concrete (GFC). Twelve mixtures were tested for fresh properties (flowability, density), mechanical performance (compressive and flexural strength), thermal insulation (thermal conductivity), and durability (water absorption, porosity, sorptivity, high-temperature resistance, freeze–thaw, and sulfate resistance). The results revealed that increasing LM content enhanced compressive strength, with the highest strength of 6.22 MPa achieved at 50 % LM and 100 % MS, representing a 202.92 % improvement compared to the reference mixture (2.06 MPa). Although the maximum …
