The need for greener construction materials has intensified research on concrete systems that can reduce carbon footprint while delivering superior mechanical and durability performance. This investigation reports on an M25-grade sustainable concrete in which 40% of Ordinary Portland Cement (OPC) was replaced by Ground Granulated Blast Furnace Slag (GGBS), reinforced with polypropylene fibers (PPF) at a constant 1% volume fraction, and modified with guar gum biopolymer (GG) at four dosages (0.05%, 0.10%, 0.15%, and 0.20% by weight of binder). A total of six mixes (M0 to M5) were prepared. Fresh concrete workability was evaluated using the slump flow test, while hardened properties were characterized by 7-day and 28-day compressive strength on 150 mm cubes and flexural strength on 100 × 100 × 500 mm prisms. Durability performance was assessed by exposure to 5% sodium sulphate solution for 28 days, recording mass loss and residual compressive strength. The experimental results revealed that compressive strength improved progressively with guar gum content up to 0.15% and then declined, whereas flexural strength followed a similar parabolic trend. The optimum mix (M4, with 0.15% GG) achieved a 28-day compressive strength of 33.25 N/mm² (22.2% higher than control) and a flexural strength of 3.82 N/mm² (20.1% improvement). Durability results showed that mass loss reduced from 4.82% in the control mix to 1.85% in M4, and residual strength increased correspondingly. A multi-linear regression model and a classification scheme were developed in Python to relate the three variables (GGBS, PPF, GG) to the strength outputs, achieving a coefficient of determination of R² = 0.978 for compressive strength and R² = 0.961 for flexural strength. The study confirms that the synergistic action of GGBS, PPF, and guar gum produces a denser, crack-resistant, and sulphate-resistant concrete and establishes 0.10–0.15% GG as the optimum biopolymer dosage for structural applications.
