Abstract

Alkali-activated materials, renowned for their cost-effectiveness and environmentally friendly characteristics, are emerging as promising alternatives to conventional cement-based materials in the construction sector. This study formulates a tailored alkali-activated mortar (AAM) by integrating waste foundry sand (WFS), with a specific focus on optimizing its applicability for 3D printing purposes. AAM compositions were formulated with different percentages (0%, 15%, and 30%) of river sand replaced with WFS. Incorporating WFS improved the strength of AAM, with a 30% improvement observed at the 30% sand substitution level. The rheology of the AAM mix was examined at different water/binder (W/B) ratios, varying from 0.4 to 0.6, with increments of 0.25. The plastic viscosity showed a declining trend as the W/B ratio rose, whereas the yield stress initially rose with the W/B ratio until it reached a specific threshold, beyond which it declined. Moreover, the optimal rheological properties of AAM containing 0%, 15%, and 30% WFS were achieved at W/B ratios of 0.47, 0.50, and 0.55, respectively.
