This paper reports an experimental study on the design of self-compacting lightweight concrete using acidic pumice with different powder materials. For this aim, nine self-compacting lightweight concretes were designed with inclusion of two different fine aggregates and different powder materials. This way, two groups of concrete were designed. First group was composed of single type of aggregate which is acidic pumice from Bitlis Region with barite powder, fly ash powder and pumice powder inclusion, while the second group was generated with river sand as a fine aggregate and acidic pumice from Bitlis Region, as a coarse aggregate with the same powder addition. In the design process, slump-flow, V-funnel and L-box tests were applied to determine the fresh properties of self-compacting lightweight concrete. After the design, test of compressive strength, which is one of the most important parameters of concrete, was applied to all self-compacting lightweight concretes in early age. Moreover, ultrasound pulse velocity test was also performed on all concrete series at the same ages.
