Abstract
The economic costs of construction have become largely unbearable today. In a bid to mitigate these costs, civil engineering faculties and stakeholders across the world have endeavoured to produce recyclable and resource saving concrete for construction purposes. Most of the environmental problems are caused by the deposit of waste to the environments in which marble shaping is part. Both stone slurry and solid wastes are generated from the marble stone slurry and with the huge discharge of marble waste locally, emphasizes has been placed on the reuse of the waste material. This research investigates the utilization of marble dust powder in concrete, where marble dust at varying percentage (0%, 15%, 25% & 35%) with replacement by sharp sand was added in M15 grade and water cement ratio 0.50 was kept constant in the concrete mixes. The quality, performance and reliability of the concrete where tested by the compressive and split tensile strength of 7, 21, 28 and 56 curing days. The results of the laboratory work showed that marble dust powder replacement with cement increased in strength up to 25% for both resistance to compressive load and tensile strength of concrete
