This research article intends to put forward the analysis report on effect of using Nano clay and Nano Rice Bran powder in clay soil. The virgin (or) parent soil is tested for knowing their assets and then based on the optimum moisture content about 0.2%, 0.4%, 0.6%, 0.8%, 1%, 1.2%. of Nano Clay and Nano Rice Bran powder added. First all the required engineering property of the clay soil is determined followed by them Atterbergs limit, Standard proctor compaction test, California Bearing Ratio test for soil with different additives were determined. The significant improvement while using nano additives were noted. The Liquid Limit of virgin soil is 44% and while adding Nano Clay and Nano Rice Bran powder 0.2% on each trial the Liquid Limit decreases to 37% and 39%. Likewise the plastic limit, shrinkage limit also decreases on increasing additive content. Optimum Moisture Content (OMC) decreases on Nano material addition. For Nano Rice Bran and Nano Clay the optimum value for OMC is 0.6% and 0.8%. The CBR value is determined for analysing the sugrade strength. Maximum value obtained at 1% of Nano Clay and Nano Rice Bran powder addition. On evaluating the overall outcomes, it is clearly known 1% of Nanomaterial is enough for achieving good stabilized soil
