Abstract: To concrete structure, the marine environment is much more inclement than terrestrial environment and the corrosion is even more serious. Chloride and sulfate will damage the concrete layer and rust the reinforcing steel bar. As the reaction medium and transporter of the chloridion and sulfate ion, water permeating into the concrete is the essential condition of the corrosion damage. CN2000B material has excellent waterproof and anticorrosive property and can effectively prevent the concrete structure from deteriorating and extend its service life in the marine environment.
Key words: concrete structure, chloride, sulfate, corrosion, CN2000B

Foreword
　　Dubai is a dreamy place. Tourists from around the world are attracted by a 7 Star Hotel, the Burj and hundreds of star hotel in the United Arab Emirates. By report, many hotels will be built every year. As the Burj was built on an artificial island, these buildings may be built on waterfront or island. It is understood that the summer (from April to October) in Dubai is very hot with air temperature of 40~45°C and relative humidity (RH) of over 90%. Magnificent concrete building structure is faced with the erosion from the seawater, the sea breeze and the underground soil in the environment condition of the high temperature and high humidity. The hotel investors, designers, builders, operator, etc., are seriously concerned about durability of concrete building structure.
