In this study, Self-Compacting Concrete (SSC) was produced by using Fly Ash (FA) and Marble Powder (MP), which reduces the amount of cement, causes less damage to the environment and has some superior properties compared to normal concrete. The changes in the physical and mechanical properties of the produced SSCs with increasing age were investigated. CEM I 42.5 R cement was used as a binder in the production of SSC. It was used with FA and MP cement at the rates of 10%, 20% and 30% by weight. In general, a high percentage of powder material is needed in the production of SSC. Instead of obtaining the required amount of powder material from binder material, Stone Powder (SD) was preferred as filling material and hyperplasticizer additive was preferred as chemical additive. In the design of the SSC mixture, the amounts of used materials were determined in accordance with the standard. The produced SSCs were cured in the standard curing pool until the day of the experiment. 7, 28, 56 and 90 days compressive and splitting tensile strengths were determined as mechanical strength. As for the physical properties, water absorption, porosity, unit weight, capillary water absorption, ultrasound pulse velocity and electrical resistivity values at 28, 56 and 90 days were determined as a result of the experiments. Moreover, it was observed that the mechanical strengths increased with the increase of concrete age, while the ideal ratio was determined as 20% for both mineral admixtures.
