Optimal performance was found at 5% wheat straw ash substitution, achieving 48.42 MPa compressive strength.
A 90-day compressive strength increase of 4.7% was observed with wheat straw ash when replacing cement.
Multi-technique analysis including SEM, XRD, TGA, and FT-IR confirmed wheat straw ash's pozzolanic reactivity.
Wheat straw ash use can reduce agricultural waste burning and improve air quality, aligning with circular economy principles.
