16、rosion Using Half Cell Techniques-w.J.BRXCKEV 185 Overview The deteriorating infrastructure is a topic of major importance throughout the world.Steel reinforced concrete is one of the most widely used construction materials,and as such,many of the deteriorating structures are of reinforced concrete.This has occurred even though steel-reinforced concrete is very durable,because this very durability has led to its use in aggressive environments.The purpose of the symposium,in which the papers in t
