    Influences on the transport properties of a range of South African marine concretes
    (2010) Githachuri, Kung'u; Alexander, Mark Gavin; Moyo, Pilate
    It is widely understood that the transport properties of marine concretes affect their potential durability in their service environment. The critical deterioration effect on such concretes is corrosion of embedded steel promoted by chloride ion ingress into the concrete. The occurrence of such deterioration and the rate at which it occurs depends on the quality of concrete, the aggressiveness of the particular marine environment and the coupling between the two. This dissertation presents the results of an experimental study done to compare different South African marine concrete making materials sourced from Cape Town, Port Elizabeth and Durban. The materials are typically specified for reinforced concrete structures in these urban marine regions.
