Self-Compacting Concrete (SCC) has more attention because of its ability to compact without the need of internal or external vibration. The placing of normal conventional concrete is difficult in reinforcement confinement places and also the strength of the concrete is low when it is subjected to severe exposure condition. In order to overcome these effects the admixtures were used in the concrete to increase the strength and durable properties. As the concrete is flow able, SCC has more workability and by the addition of mineral admixture like fly ash and silica fume, the concrete will attain more strength and durable, so that the concrete will behave as Self Compacting High Performance Concrete (SCHPC). In this paper the tests on fresh SCC such as slump flow test, V funnel tests and L- box tests were presented and the test results were discussed. Cubes and cylinders were made with different percentage replacement of cement with fly ash and silica fume and strength tests such as cube compressive strength at 7th and 28th days and split tensile strength test at 28th days was performed. The test results showed that the 30% replacement of cement with combination of fly ash and silica fume gave better strength when compared to that of the normal conventional concrete.
