ABSTRACT
Although materials, mix proportions, and concreting practice for modern marine structures have considerably improved during the last two to three decades, it is useful to review briefly the composition and properties of ordinary structural concrete because, from the turn of the century until the 1940s, most marine construction was carried out with this type of concrete. Knowledge of the composition versus property relationships in ordinary concrete not only will help the understanding of the causes of deterioration of old sea-structures, but also will provide a background for recent advancements in concrete technology.
