The construction industry is a significant contributor to environmental degradation due to the extensive use of Portland cement, which emits substantial CO₂ during production. This study investigates the feasibility of partially replacing cement with hyposludge (a byproduct of the paper industry) and fly ash (a byproduct of coal combustion) in concrete mixes. Concrete specimens were prepared with varying percentages of hyposludge and fly ash, and their mechanical properties, including compressive strength and split tensile strength, were evaluated. The results indicate that a 20% replacement of cement with a combination of hyposludge and fly ash yields optimal strength characteristics, suggesting a sustainable alternative for cement in concrete production.
