Researchers tried almost every conceivable material to be mixed in concrete to alter some of its properties. High strength self-compacting concrete (HSSCC) is one of the concrete innovations that have a high quality standard. This paper reports an experimental study of the influence of metakaolin and marble powder on the mechanical properties of high strength self-compacting concrete (HSSCC). This type of concrete has a high compressive strength and can compact without tools. Parameters that are about to study in this research are fresh properties and mechanical properties of HSSCC. In this research, trying to prepare high strength self-compacting concrete mix design without decreasing its mechanical characteristic, where metakaolin and marble powder replace cement in percentages of 5% ,10%,15% by weight of the control cement content. In this study used two types of superplasticizers which are conplast sp 430 which is naphthalene based superplasticizer and the other one is pc based superplasticizer. Several samples were prepared to study the effect of the superplasticizer on concrete and the result and noted. Fresh properties of the self-compacting concrete tested such the test that are perform are slump-flow, l-box test, v-funnel and all gave the positive result and for the compressive strength using metakaolin with pc based superplasticizer at all three percentages such as 5%,10%,15% of cement replace with metakaolin gives good result at 7 and 28 days after curing. But for the compressive strength using marble powder with using naptha based plasticizer it didn’t give result up to the design expectation at both 7 and 28 days with all 5%,10%,15% replacement of cement. Flexural and tensile strength are also tested.
