The rapid increase in industrial and agricultural waste poses ecological risks and threatens vital resources. To mitigate greenhouse gas emissions, global efforts promote alternative cementing materials. Fly ash, a byproduct of coal combustion, offers a viable substitute for cement in structural concrete. This study comprehensively analyzes fly ash’s impact on concrete properties. Various fly ash replacement percentages were investigated through curing at 28 and 56 days. Testing revealed that 15% fly ash replacement yielded the highest compressive strength (3699 psi), signifying an optimal replacement level. Ultrasonic pulse velocity testing indicated a proportional decrease in concrete quality as the replacement percentage increased.
