The causes of degradation of the durability of marine structures are analyzed and the principle of crack resistance and impermeability of concrete added with UEA expansion agent is presented as well as the performance of such concrete.It is proposed that the shrinkage compensated concrete added with adequate expansion agent is a new way to enhance the durability of marine structures,which should be used in closure blocks in concrete marine works,mass concrete in the floors of docks and slipways,post cast joints and cavity repairs.
