Abstract

The ability of MSWIBA as a precursor for geopolymer mixtures amenable to 3D printing is explored in this research. In geopolymer binders, the MSWIBA is utilized in part substitution of fly ash. Investigations are conducted into how the MSWIBA content affects the fresh qualities of printed formulations, particularly setting time, rheological characteristics, and flowability. Additionally, using different amounts of MSWIBA in the mixture, the hardened characteristics of 3D printable MSWIBA geopolymer concrete are assessed. According to the test findings, the MSWIBA content in the mix has enhanced the fresh characteristics of the optimum 3D printed mix. Excellent early age yield stress and apparent viscosity are demonstrated by the optimum mixture with MSWIBA. The incorporation of MSWIBA up to 10 % has enhanced the compressive strength of 3D printable geopolymer concrete samples, whereas higher MSWIBA concentrations has led to a reduction in hardened properties. Lastly, the suggested one-part geopolymer can lessen the carbon emission and embodied energy by up to 11–38% in comparison with OPC concrete.
