This study has been undertaken to investigate the Concrete plays an important role and large stones are used in many construction projects. Natural river sand, one of the main components of the stone, is becoming cheaper due to high transportation costs. The use of large resources can cause environmental problems. Better alternatives and new materials are needed to overcome these problems. Quarry dust is the waste generated during quarrying. Recently it has become more popular as a good replacement for good mix. Additionally, the use of quarry dust as aggregate reduces production costs by partially replacing hydrosand. The design mix of M20 class concrete modified with 0%, 50% and 100% sand was taken into account and slump and compressive strength tests and laboratory analyzes were carried out. In this case, the hardening behavior of the stone is examined using quarry powder. This project uses M20 concrete mix ratio. Various materials were used to cast the 150mm concrete slab. Treated cells were crushed on days 14 and 28 to measure compressive strength. The results showed that the compressive strength of concrete made from quarry dust increased with days without much change in compressive strength. In addition, this study will help us see the differences in the composition of different stones at different times by reaching the good properties of different stones.
