Abstract : The synthesized aggregate manufacturing involves the geopolymerization technology and the direct pressure application approach to obtain coarse aggregates. This current study combined industrial-grade FAS, GGBS, Fine Aggregate (FAgg), Sodium Hydroxide (NaOH), and Sodium Silicate (Na2SiO3) to create a geopolymer mortar. Initially, geopolymer mortar cubes of 150 mm were created by applying geopolymer technique. Subsequently, these cubes were broken down into coarse stones having angular forms at 7 days. The artificially synthesized aggregates were employed as geopolymer coarse aggregates (GCA) in lieu of conventional coarse aggregates for the production of geopolymer aggregate concrete (GPAC). Since experimentation alone cannot solve the problem of data scarcity, a feed-forward network is used to address this challenge and is modeled as a regression problem. The issue of data insufficiency was overcome by creating 1000 synthetic data points with the Conditional Tabular Generative Adversarial Network (CTGAN) algorithm. The proposed approach achieved a mean squared logarithmic loss of 0.0277 and an R2 score of 0.5491.
