A mini guideline study for fly ash-based alkali activated foam masonry units

Abstract

This study examined the preparation of fly ash-based foam geopolymer recipes with the experimental design method and data analysis with the SPSS program. A total of 54 prescriptions were used in the studies, which investigated six different variables. Strength, density, and thermal conductivity analyses were performed. Values were in the range of 0.57-2.75 MPa for strength, 344-592 kg/m3 for density, and 0.089-0.132 for thermal conductivity. Three variables were identified with each having the most significant effect on strength and density values. H2O2, curing temperature, and expanded perlite had the most effect on strength, while H2O2, curing temperature, and alkali concentration had the most significant effect on density. Most influential parameters are plotted on ternary graphs to ensure that the foam concrete (CLC) masonry units used in all types of masonry walls, whether load-bearing or not, can operate under the specified performance conditions.
