The percentage of the ocean on the Earth’s surface is 71%. Hence seawater is available in abundance. If the freshwater is replaced by seawater, there would be sustainable development in the construction industry. In this study influence of the composition of Portland cement - fuel ash - metakaolin – silica fume binders partially mixed with seawater on the strength and durability of the concrete have been investigated. The percentage of replacement of freshwater by seawater was 5%, 10%, 15%, 20%, 25%, and 100%. The effects of concrete mixing with seawater on compressive strength and its durability were studied. https://www.arce.ir/article_171457_09097ad6a1dd6a09ea0c486c284f7844.pdf
