Abstract Researchers investigate alternative materials for concrete production because of rising market need for sustainable cost-efficient building materials. Marble dust serves as a suitable alternative in concrete applications since it originates from the marble industry while creating environmental waste management hurdles. This study examines marble dust integration into concrete mixes through investigations into concrete mechanical properties, which change when marble dust proportion varies. This study identifies the optimal level of marble dust substitution that enhances strength development, improves resistance properties and maintains adequate workability. The research used concrete specimens containing various quantities of marble dust to replace cement according to weight ratios between 0% to 20%. Standards tests assessed the mechanical behavior of modified concrete through measurements of compressive strength in addition to split tensile strength evaluations. The test outcomes showed that marble dust implementations impact concrete strength properties in both compressive and split tensile aspects. The compressive strength and split tensile strength of concrete mixtures improved with marble dust content up to 16%, primarily due to the filler effect and enhanced particle distribution within the cement matrix. However, replacement levels reaching up to 20% resulted in a decline in strength, as the reduction in cementitious components limited effective participation in the hydration process. Studies indicate that moderate replacement of cement with marble dust not only enhances concrete properties but also reduces environmental impact by lowering cement consumption. The construction industry benefits from this sustainable substitution, as the use of marble dust helps minimize waste generation and promotes eco-friendly practice.
