Abstract: Marine exposure conditions provide an aggressive environment for reinforced concrete structures, mainly due to the occurrence of chloride-induced reinforcement corrosion. There are several influencing factors, but despite a lot of research little is known about the influence from variations in the concrete compositions. Therefore an exposure program has been made, where concrete specimens, made from four concrete compositions, have been exposed at a single marine tidal exposure zone in Persian Gulf, along with a parallel study under laboratory conditions. In this paper, chloride diffusion of concretes under field conditions contains silica fume (5%, 7.5% and 10%) as a replacement of cement compared with the same specimens under laboratory conditions.

Keywords: Chloride diffusion, Silica fume, exposure condition, laboratory condition
