This study presents a broad and systematic experimental investigation into the development of a new generation of lightweight geopolymer mixtures, providing a clear, data-driven pathway for optimized material design. The core novelty of this research lies in the innovative and cost-effective use of raw perlite as a base material, eliminating the need for the energy-intensive processing required for traditionally expanded perlite. A major strength of this work is the comprehensive and systematic assessment of how Glass Fiber (GF) and Hydrogen Peroxide (H2O2) influence geopolymer mortars and pastes, evaluating their effects on compressive strength, flexural strength, and thermal conductivity across a broad range of mixture compositions. It is recommended to use 45 % water/perlite, 0.25 % H2O2/perlite and 0.3 % (3 mm length) GF/total mixture to obtain both durable and lightweight mortars. However, it is emphasized that H2O2/perlite over 0.5 % and GF/total mixture over 0.3 % should be avoided in the mixtures. The systematic optimization process led to the identification and detailed characterization of optimum mix compositions, offering high practical value for lightweight construction materials suitable for such as wall panels, insulation boards, and roofing elements.
