Enhancing cement concrete's strength and durability is crucial for sustainable infrastructure
development. This study investigates the effects of metakaolin (MK) and waste glass (WG) as partial
cement and sand replacements, respectively, along with glass fibers (GF) on the mechanical properties
of concrete. Five mix designs (S1–S5) were developed with varying metakaolin content (2%, 4%, 6%,
8%, and 10% of cement weight), maintaining a constant 0.50% GF and optimized WG replacement.
Compressive strength tests at 7, 28, and 91 days revealed a consistent improvement with increasing
MK content, with S5 (10% MK) exhibiting the highest compressive strength (21.27 MPa at 7 days,
28.57 MPa at 28 days, and 29.81 MPa at 91 days). Split tensile strength results followed a similar
trend, with S5 achieving the maximum values across all curing periods
