Concrete, known for its brittleness, bending strength, and resilience, can be enhanced by incorporating Ground Granulated Blast Furnace Slag (GGBS). This paper demonstrates mathematical models utilizing algebraic functions such as Gaussian, Power, Fourier, Exponential functions employed to establish correlations between the percentage of GGBS and mechanical attributes involving compressive strength, flexural strength, and split tensile strength. Additionally, custom equations were considered to capture specific characteristics. Including GGBS in concrete has been shown to improve its mechanical strength, making it an attractive option for construction applications. Statistical analysis was conducted using GGBS powder as a supplement, with concrete mixtures ranging from 30% to 42.5% GGBS content at 2.5% increments, based on a volumetric basis and a water-cement ratio of 0.4. The experimental results revealed that even a small variation of 2.5% in GGBS content significantly enhances the mechanical characteristics of the concrete. GGBS concrete exhibited notably higher compressive strength, split tensile strength, and flexural strength than traditional concrete. The findings of this study contribute to the understanding of the relationship between GGBS content and mechanical properties, facilitating the optimization of GGBS concrete mixtures for enhanced performance.
