Abstract : In recent times nanotechnology has given rise to new wave of material science in construction industry. Strength and durability of PT slabs play major role in buildings construction, which in turn can improved by using Nano-concrete in PT slabs. In this research study, an effort is made for the study of structural performance of post- tensioned concrete slabs manufactured using Nano-concrete (Post-Tensioned Nano- concrete Slab). To study structural behavior firstly the theoretical modeling of Post- Tensioned Nano-concrete slab is created by using ANSYS Workbench 19.2. By interchanging properties of concrete to Nano-concrete properties finite element analysis of Nano-concrete slabs is carried out and then comparison between ordinary PT slab and Nano- concrete PT slab is carried out for load deflection characteristics. After finite element analysis actual experimental investigation is performed to study actual behavior of Nano-concrete PT slab. In this thesis Nano-concrete containing graphene (0.03% of cement) and Nano-silica (2.5% of cement) is used as material for PT slab. PT slabs are tested as per IS method. From the results obtained from finite element analysis and experimental investigation, graph is plotted between load v/s deformations in sleeper. Results of both experimental tests as well as FEM analysis show better results in Nano-concrete PT slab than conventional PT slab. Results shows higher load carrying capacity in Nano-concrete PT slab than conventional PT slab. Also, Nano- concrete PT slab has higher yield deflection than Conventional PT Slab
