Seawater concrete is a “concrete produced by using seawater as mixing water or curing water, or both”. Why shall we use seawater for concrete production? Nowadays, only fresh water is used in concrete production in almost all countries. However, it is surely estimated that in mid- 21st century, we human beings are facing water scarcity, water stress and water crisis in many countries, areas in the world. Due to the background, quick modernization in many developing countries, and skyscraping increment in the world population. In most of the world standards, sea water is prohibited to be used in concrete production, in RC and PC. However, it is fact that there are many existing structures made of “seawater concrete” since more than five decades ago. Japanese examples listed in this book are: a light-house located in Ukushima iasland, Nagasaki prefecture, and a port facility of pre-packed concrete in Tajiro-port, Tottori prefecture.
