POSSIBILITY OF SEA WATER AS MIXING WATER IN

2017-10-27  Abstract. In the near future, fresh water will be very difficult to get and scarce. It is said that in 2025 half of the mankind will live in the areas where fresh water is not enough. Also, UN and WMO are predicting 5 billion people will be in short of even drinking water. Also, in the present, there are some areas where sea water or chloride contained sand are used as mixing water with or without intension. The authors believe that the possibilities of using sea water as mixing water in concrete

2017-2-28  problem of shortage of clean water in the distant island, and saving the fresh water over the world, this research seeks to use sea water to produce concrete. One of the requirements in making concrete (both structural and non-structural) is fresh water. However, the data of United Nations and WMO (World Meteorology Organization) predicted around 5 billion people will be in a lack of fresh water at the end of 2025. Hence, the use of fresh water only for primary needs. And it is important for the world of concrete construction to seriously study the possibility of sea water as mixing water in making concrete (called seawater concrete) which can minimize usage of fresh water and help the areas that have difficulty fresh water to accelerate development infrastructure by using concrete
