Abstract
In this paper, the most important observations of the effect of seawater (SW) and/or sea-sand (SS) on the properties of concrete are presented and critically reviewed. Concrete is responsible for about 9% of global annual industrial water and almost 70% of the extracted natural sands use. During last decades many researchers focused on replacing them by SW and SS and many promising results have been reported. SW and SS affect the fresh concrete properties by decreasing setting time. They increase the early age strength while their effects on 28-days and long-term strength is insignificant. Durability of seawater sea-sand concrete (SWSSC) and corrosion resistance of embedded steel can be improved by using supplementary cementitious materials.
