This study assessed the impact of addition phase change materials (PCMs) under trade name Micronal 28S on properties manufactured geopolymer foams. is used as a functional component in foams (insulation materials), foamed building materials, and for temperature regulation to improve thermal comfort indoor climate. The melting point 28 ± 2 °C, heat fusion ∼140 J/g. As part research, mixtures containing PCMs form slurry were prepared shares 0, 5, 10, 15 wt %. Geopolymers produced based fly ash. foaming process was carried out using hydrogen peroxide (H2O2). Physical, mechanical, analysis microscopic microstructure evaluated. introduction into matrix conducive obtaining ultralight with density about 200 kg/m3. share PCM increases, insulating samples increase by reaching conductivity coefficient λ 0.057 W/m*K. Simultaneously, specific increases up 1.105 kJ/kg*K. Microstructure confirmed that tends agglomerate decrease pore size. material reduces mechanical geopolymers. However, according EN 998-1 standard, conditions requirements be realized construction met reference sample one 5 % 28S. content this publication addresses issues both science engineering. Although other authors have conducted research various work first use produce excellent insulation properties.

This research used fly ash and slag to create geopolymer foam concrete. They were activated with an alkali, resulting in a chemical reaction that produced gel strengthened the concrete’s structural integrity. The experimental approach involved varying content precursors at incremental percentages (10%, 30%, 50%, 70% 90%) subjecting mechanical activation through planetary ball mill distinct rotational speeds (380, 400, 420 440 rpm). investigation discerned particle structure exert discernible influence on macroscopic properties, including flowability, air generation height, compressive strength, dry density microstructural characteristics such as pore distribution hydration product arrangement Employing analytical techniques X-ray diffraction (XRD) scanning electron microscopy (SEM), it was deduced diminishing correlates enhancement strength. Furthermore, specific strength of concrete reached peak 0.041 when rotated rpm, manifesting lightweight high-strength outcome.
