Abstract: The principle target of the study is to evaluate the probability of using nano silica as cement replacement materials and copper slag as fragmented fine aggregate in Self- compacting concrete. The degree of the present study joins the examination of convenience, mechanical and quality properties of Self-compacting concrete combining distinctive replacement levels of above materials. Nano silica is another mineral admixture with particle size in the Nano metric range and high express surface region. Its potential points of interest in cement based materials are not totally recognized in light of limited asks about in the field of Nano fabricated cementations composites. Concrete with suitably dissipated Nano silica of perfect sum realizes incredible quality and solidness properties. Use of mineral admixtures reduces the measure of cement for concrete generation which, accordingly, diminishes the outpouring of CO2 into the air. The degree of Nano silica replacement is 0%, 0.5%, 1%, 1.5%, 2%, 2.5% and 3% by weight of cement. A relentless water-spread ratio of 0.31 is gotten for all the concrete mixes. The usefulness of SCC mixes are kept up in the hang extent of 25 – 50 mm by fluctuating the substance of super plasticizer. The perfect measure of Nano silica, is managed by coordinating usefulness, mechanical and strength tests. Nano silica improves the early nature of concrete on account of its high Pozzolanic reactivity. Extension of Nano silica improves the quality at 1 – 3 days of calming. This is credited to the high unequivocal surface zone of Nano silica.
