Abstract: Geopolymer concrete is established to have brilliant designing properties with a decreased carbon impression. Geopolymer with fibers has gained prevalence in recent years for use in concrete, for the most part, inferable from their low cost and outstanding individuality. In this examination, Fiber-Reinforced Geopolymer Concrete (FRGPC) is utilized as a binder with the impacts of the intrinsic sulfate solution in Gypseous Soil. GPC blend is included with alkaline activators, for example, NaOH and KOH with molarities [M. Z. N. Khan, Y. Hao, H. Hao and F. U. A. Shaikh, Cem. Concr. Compos.85 (2018) 133; P. Sukontasukkul, P. Pongsopha, P. Chindaprasirt and S. Songpiriyakij, Constr. Build. Mater. 161 (2018) 37; Y. Alrefaei and J.-G. Dai, Constr. Build. Mater. 184 (2018) 419] and hybrid fibers (steel and polypropylene) with the fiber content of 0–0.16%. Fibers are added to upgrade the strength to the concrete to meet given functionality necessities. The Gypseous Soil is taken with the percentage of G13,G25,G54, to assess the effects, compressive strength, ductility, collapsibility potential, and coefficient of penetrability tests were performed with a soaked and unsoaked solution. These outcomes are validated with the assistance of an Artificial Neural Network (ANN) optimization algorithm. The validation results played out that ideal precision and high strength of the activated solution. At long last, the simulated outcomes give better execution compared with existing papers.
