Reasonable and standardized use of local and waste resources is of great importance for the economic development in the world. The utilization of waste materials can result in enhanced properties and eco-friendly concrete, at the same time. In this study, it is aimed to evaluate the effect of olive waste ash on the mechanical and fracture properties of self-compacting concrete. For this purpose, self-compacting concrete mixes were prepared by the utilization of olive waste ash, in three different proportions and with two different dosages of superplasticizer. Alongside compressive and tensile strengths analysis, a series of three-point bending tests on notched beams were conducted for all mixes. Moreover, initial defects of all self-compacting mixes were evaluated by using the X-ray computed tomography method. Findings showed that using olive waste ash in self-compacting concrete mainly affects the tensile strength and fracture energy for the two different contents of superplasticizer.
