Life of a structure is basically defined by its durability. Over coarse of time, concrete carbonation and corrosion of steel reinforcement leads to weakness in structural elements and hence reducing its useful life. Addition of fibers in concrete can act as a barrier and prolong the activation of this process. In this study, low quality fly ash was added to concrete to check it effect on durability of concrete. It was found out the addition of low quality fly ash with an activator does have positive impact on carbonation and reinforcement corrosion resistance. Keywords-Durability, fly ash, fibers, carbonation, corrosion
