Study on the durability of concrete structures bridge

The environmental characteristics of coastal areas north of ice,the impact of the durability of concrete bridge structures of several problems.From the high volume of concrete mixed with ordinary powder,to the freezing and thawing,water erosion durability of concrete structures under combined evaluation method and engineering measures,and proposed site durability of concrete mix adjustment methods.The results show that:the first big content with the durability of ordinary concrete mix slag technology to improve resistance to chloride ion penetration of concrete;freezing and thawing,water erosion durability of concrete structures under combined evaluation method and study engineering measures,similar to sea water can double freezing and thawing and erosion play bridge construction under reference;durability of concrete materials and durability compared with the correlation,to simplify the durability of concrete construction durability of quality control procedures,and effective guidance to the durability of concrete construction.
