The sugar industry serves as the cornerstone of agriculture in Solapur district, boasting an impressive 44 sugar factories. Solapur district also stands as the leading producer of sugarcane in India. Within the sugar production process, cane molasses emerges as a local byproduct, alongside bagasse, pressed mud, and mud-laden wastewater. Molasses, one of the four types of sugar byproducts, contributes to the increased fluidity of fresh concrete and effectively retards the hardening time of cement paste. For the purposes of this study, molasses obtained from sugar refineries was utilized. The addition of molasses in varying dosages (0.25%, 0.50%, 0.75%, and 1.25% by weight of cement content) had a pronounced impact on both the initial and final setting times of concrete. Workability tests were conducted on freshly mixed concrete that incorporated these four different molasses dosages. Compressive strength tests were carried out on hardened concrete blocks after 7 and 28 days, along with flexural and split tensile strength tests. Comparisons were made between the control mix and the concrete mixtures containing molasses. The results indicated a slight increase in the strength of the concrete with molasses as it aged, except for the early stages of development. This suggests that the presence of molasses in concrete has the potential to enhance its long-term strength and durability.
