Abstract Ultra-high-Performance concrete (UHPC) is a cementitious composite material, composed of an optimized gradation of granular constituents, a water-to-cementitious material ratio. In the engineering industry, the improvement of existing material allows for technological advancement and the construction of more reliable structures without over design. In India, UHPC is used rarely on demand of construction and requirement of high strength. It is still not widely used due to its higher cost, lack of labour contractor experience and the absence of standard provision. Globally, Ultra-high-performance concrete, a material widely utilized in heavy structural construction is a cheap and dependable material that can be studied to reach its optimum performance. Nanomaterials have high superior mechanical properties due to very small particle size from 1nm to 100nm were added to enhance the strength of Ultra high-performance concrete (UHPC) and to reduce its shrinkage. It is also used as cement replacement material to reduce the amount of cement in UHPC mixes. Shrinkage is defined as decrease in the length or volume of a material resulting from changes in the moisture content or chemical changes. In this project, various types of shrinkage like Drying Shrinkage, Autogenous Shrinkage, Plastic shrinkage for the UHPC will be evaluated through experimental model by utilizing relevant methodology as per the standard available. Based on the experimental results, assessment of the shrinkage will be analyzed and effect of shrinkage on UHPC will be understood. To counteract the social and industrial need of construction industry, this project gives important information and outcomes in terms of concrete mix proportioning, achieving targeted compressive strength of concrete, shrinkage behavior of UHPC and its related properties. The outcome of this project provides technical understanding which benefitted a lot to these ultra-modern construction industry stakeholders.
