Abstract: Use of high perforformance concrete in present days is increasing as conventional concrete does not meets the requirement. Hence it is necessary to develop high performance concrete. The high performance concrete is one which has the characteristics like workability, high strength & durability. These characteristics are not found in conventional concrete. From the recent study ,,,, it is found that the high performance concrete can be developed by using supplementary cementecious materials & high quality superplasticizers. Use of Nano materials is gaining importance due to its vital characteristics, these materials helps in developing high performance concrete. This study aims at developing high performance concrete using Nanosilica. Initially, M60 grade concrete (high strength concrete) is designed and prepared with and without Nano silica. Then it is proposed to make this concrete as high performance concrete by using high quality superplasticizer and a better packing of coarse aggregate(40% 10mm downsize &60% 20mm down size).The test results shows that slump higher than 210mm , strength 68.44 to 75.11MPa and better resistance to water obsorption.
