المستخلص: In the process of the extraction oil from the oil rocks a huge amount of waste dust formed due to crushing and grinding of the virgin oil shale , causes an environmental pollution leads a hazard diseases to people ,animals and ruin the plants. So to eliminate the above mentioned oil shale waste , the produced grinded oil rocks in form of an Oil Shale Powder (OSP), can be used as an admixture material , in producing cement concrete bricks. To study the possible use of OSP in producing concrete mix, an experimental tests were carried out . In this research, an OSP was used as an admixture of cement. The main aim of this study is to investigate the compressive strength and setting time properties of concrete mix with OSP (as a partial replacement of cement) . Experimental results showed that the compressive strength of concrete cubes that containing 5, 10 and 15% of virgin oil shale (by weight) , decreased by 14.2, 20.1 and 28.8% compared with the conventional concrete cubes, respectively after 7 days water curing , and also decreased by 9.1, 15.5 and 23.2% respectively after curing of 28 days. The reason of decreasing the compressive strength of concrete mix with OSP , is due to the lower content of ferrous components of OSP in their chemical compositions, also due to the existed oil in the voids of oil shale , that leads to separation between cement and other components of concrete mix. Setting time of cement paste increased by (25), (30) and (40) min when use concrete mix with 5, 10 and 15% OSP comparing with the conventional concrete mix, due to the delay of cement hydration. The OSP existed in the concrete strengthen the properties of its components. The final conclusions showed some perfections when utilizing cement with OSP in long term curing.
