Concrete with high durability and strength using seawater and sea sand

The technology to make concrete with high durability and strength using seawater and sea sand was announced. After using sea sand as the fine aggregate and seawater as the kneading water, blast furnace cement and a special admixture are used. In addition to increasing the initial strength due to the effect of the admixture, the water permeability is significantly reduced due to the chemical reaction with seawater, and it seems that it exhibits higher durability than concrete kneaded with fresh water. It can also be applied to reinforced concrete structures if the reinforcing bars are devised and reinforced. It seems that the construction cost can be reduced by 10% compared to the case where land sand is transported to the coastal areas and remote islands to make concrete.
