      abstract = {This study focused on durability behaviour of hardened state properties of Ultra High-Performance concrete reinforced with alkaline glass fibers at varying percentages (0.5, 1.0, 1.5 %). Increasing strength, reducing cost and shrinkages resulting from cement volume, can be achieved with the partial replacement of cement with a cementitious material called Nano-silica. In order to reduce void, the Particle Packing Method of mix design was adopted for the design of specimens. The durability of the hardened state concrete after curing in percentages of MgSO4, compressive strength tests were carried out on the specimens to ascertain concrete exposure to sulphate attack. Magnesium sulphate attack showed insignificant loss of compressive strength at 4%, 8% and 12% concentration for 56 and 90 days in the Ultra-High Performance Fiber Reinforced Concrete. Results shows that the possibility to produce Ultra-High Performance Fiber Reinforced concrete using locally available materials if they are carefully selected to achieve a minimum compressive strength of 150Mpa at the age of 28 days. Concrete durability decreases as the concentration of magnesium sulphate increases over a prolonged period of time},
