Ultra-high performance concrete is a one of the varieties with compressive strengths greater than 120 N/mm2. and formed from a special cementitious composite compound material like fine sand, silica fume, Fly ash etc. With its outstanding strength properties, ultra-high-performance concrete (UHPC) offers a very long term solution for more sustainable construction. In India high strength and high performance concretes have been utilized in the construction of nuclear power plant, Bridges, tunnel, water resources projects, high rise building framework due to its strength. But UHPC is used rarely on demand of construction and requirement of high strength. it is still not widely used due to its high cost, lack of executive agencies and the availability of standard provision. The nanomaterial has been widely used in various civil engineering applications all over the world. Nanomaterials having very small particle size, which have specific surface area of 1nm to 100nm. The development of nano-modified cement-based materials through the application of nanoparticles in civil engineering is an exciting area of study. This investigation helps identify new research and innovation in concrete materials using nanotechnology that can lead to improved mechanical properties used in UHPC. In present study, an extensive literature review have been carried out for study of a UHPC using different nano materials to demonstrate the advance concepts and properties of UHPC. In recent years, many researchers worked for improve properties of concrete by adding different nano materials and found some specific result. The implementation of UHPC using nano material with partially replacing the percentage of the cementitious material, have been studied experimentally by many researchers. This study intends to give better understanding of the fundamental properties and capabilities of UHPC using nano material to designers, builders, and other construction professionals.
