Abstract
The morphological and microstructural evolution of flyash (FA), eggshell powder (ESP), and soft soil (S) geopolymer was studied. The variable parameters for synthesis was precursor concentration (10 %, 20 %, 30 %, 40 %, and 50 %) in soft soil, whereas ESP:FA ratio as 50:50, Na2SiO3:NaOH ratio as 70:30, and curing condition as 50 °C for 7 days were the fixed parameters. The effect of these parameters on the geopolymerization was explained using field emission gun-scanning electron microscopy including an energy dispersive X-ray spectrometer and mapping. The calcium aluminate silicate hydrate gel co-existed along with the highest cementitious product. The geopolymeric gel structure filled the voids between soft soil particles and reinforced the whole matrix.
