In recent years Marble is considered one of the most important decorative building materials. Marble powder is one of the materials which severalty affects the environment and health problems. It is produced from sawing, shaping, and polishing process. This research aims to study the effect of using marble powder as partially replace of cement on the properties of concrete. The influence of using marble powder on the behavior of reinforced concrete slabs is also investigated. The main variable taken into consideration is the percentage of marble powder as partial replacement of cement content in concrete mixes. The experimental results showed that, using definite amount of marble powder replacement of cement content increases the workability, compressive strength and tensile strength. Using marble powder enhanced also the structural performance of the tested slabs as it increased the stiffness and the ultimate strength compared to the control slabs.
