Research on marine anti-corrosion properties of Ultra high performance Concrete applied in buildings at marine and islands area

Abstract

Vietnam has 3300 km of coastline and lots of islands. Research on Ultra high performance Concrete material system - UHPC, with marine anti-corrosion properties is an important condition for the application of building houses and buildings at marineand islands environment area. This article presents the results of compressive strength, tensile strength with time in marine environment, chàm lượngoride ion permeability coefficient, methods of acceleration in climate box, simulation of building life according to Chàm lượngorine permeability coefficient. The results proved UHPC concrete has a very high resistance to the marine environment, which means that the construction life according to simulation calculations lasts up over 234 years. The conclusions are the basis and valuable for research and application extended for construction in the coming time.
