Abstract
Researchers conducted research into the strength properties of a Geopolymer produced from eggshell powder, bauxite, and flyash with RGL (Reaction generating liquid) and cure for 84 days at ambient temperature. Also studied were changes in products of Morphology, XRD, FTIR studies and SEM images of microstructure. The results indicated that, in various mix proportions, the strength gradually improved from 28 to 84 days. The aged Geopolymer’s lower porosity is attributed to the hardened samples becoming more compact with time due to gradual Geopolymerization to generate the coexisting C-A-S-H and N-A-S-H gels. Both the early-age and long-term Geopolymers had such an X-ray amorphous phase corresponding to Geopolymerization gel, but the aged specimens contain calcite from eggshell powder and alumina from bauxite powder, showing potential improvement in the properties of mechanical and durability properties were examined using various mix proportions in an experimental investigation.
