This research emphasizes the manufacturing and performance testing of a green Self-Compacting Geopolymer Concrete with GGBS as the main binder. A/B ratios ranging from 0.40 to 0.60 on the rheological and mechanical behavior of SCGC in ambient curing conditions was studied. Properties of fresh concrete were evaluated by applying EFNARC-suggested slump flow, T50 cm, L-box, and V-funnel, to measure flow ability and viscosity. The mechanical performance was measured by compressive, split tensile, flexural, and modulus of elasticity at 7 and 28 days. Among the mixes, the maximum performance was noted for Mix ID-3 having an A/B ratio of 0.50 with the best values of CS (39.6 MPa), STS (4.86 MPa), FS (5.42 MPa), and MOE (31,276 MPa) at 28 days. These results verify that an A/B ratio of 0.50 remarkably improves the overall performance of GGBS-based SCGC, testifying to its potential as a green substitute for traditional concrete, thus supporting environmentally friendly construction and lower carbon emissions.
