High performance concrete (HPC) is one of the prevailing techniques which have become popular due to its mechanical and durability properties. To enhance the property, fibre reinforcement is providing with steel fibre and also overcome the insufficient curing problem due to human irregularity during the period of curing the self curing methodology have been adopted. In this study mechanical property of self curing HPFRC is examined with varies percentage of self curing agent of Polyethylene Glycol (PEG400) with a constant proportion of silica fume and steel fibre. The steel fibre of aspect ratio 50mm is adopted for minimizing the cracks in concrete and improving strength, durability, impact, toughness etc. The HPC of grade M60 is prepared with water cement ratio of 0.3 and PEG400 varies from 0% to 1.5% at 0.5% intervals with and without using steel fibres and replacing cement with 6% of silica fume. To enhance the workability of HPC, super plasticizer (conplast 430) at a range of 1.8% of cement was used. Mechanical properties like compressive strength, split tensile strength, flexural strength and modulus of elasticity were examined at 3 days, 7 days and 28 days to evaluate the optimum percentage of PEG 400 with and without steel fibre
