Durability Strategy for Structural Concretes of Shanghai East-Sea Bridge

This paper describes how the construction of a leading international shipping center, the Shanghai Deep Water Harbor began in 2002. It consists of 3 parts, i.e. over 100 container terminals on islands, the East-Sea Bridge and the New Harbor City on the mainland. East-SBridge is 32.5 km in length, starting from Little Yangshan Island of Qiqu Archipelago (Zhejiang Province), crossing the north of Hangzhou Bay, to New Harbor City in Luchao, Nanhui District, Shanghai. Due to the importance of East-Sea bridge for the harbor operation, a service life of 100 years was specified for the bridge for the first time in China, while no code or guideline for such durability was available. Extensive studies were carried out at the Shanghai Research Institute of Building Science (SRIBS) in order to establish scientific, practical, and reliable strategies to maximize the life of the bridge. The paper looks at the environment the bridge is exposed to, as well as design considerations for the concrete, the use of High Performance Marine Concrete (HPMC) and the use of quad blend cementitious binder to achieve the durability
