CRACKING AND REINFORCEMENT CORROSION IN REINFORCED CONCRETE BRIDGES
暂无分享,去创建一个
A study of design recomendations in various countries for the avoidance of reinforcement corrosion suggests that no real consensus exists on the levels of concrete cover and permissible crack width which should be specified.This paper attempts to asses the distribution of cracking, the factors of crack width, and the control of corrosion by reference to data carried out in 75 reinforced concrete bridges. And the possibility of a more rational design approach to corrosion control is discussed.
