Fundamental and Applied Research on Corrosion of Reinforced Concrete

9812757钢筋锈蚀和由此导致的钢筋混凝土结构劣化是基础设施损坏增加的主要原因之一。对混凝土强度的关注胜过对耐久性的关注，越来越多地使用除冰盐和含氯外加剂，以及在日益恶劣的环境中施工，这些都是导致近几十年来经历钢筋腐蚀的混凝土结构激增的一些因素。[混凝土耐久性危机是广泛的，特别是涉及内嵌钢筋的腐蚀，已发表的文献中充满了案例历史，表明迫切需要更好地了解腐蚀机理。这项建议的目的是建立一项关于钢筋混凝土腐蚀的整体研究。这项研究将分析腐蚀机理的化学成分，开发新的设备来确定腐蚀造成的痛苦程度，并在现场条件下测试新方法。我们将促进向业主、承包商和政府机构进行积极的技术转让。

9812757Steel corrosion and the resulting deterioration of reinforced concrete structures is one of the primary causes of increasing damage to infrastructure. A focus on concrete strength over durability, the growing use of deicing salts and chloride-containing admixtures, and construction in increasingly aggressive environments are some to the factors that have lead to the surge of concrete structures experiencing reinforcement corrosion in recent decades. [The concrete durability crisis, particularly involving the corrosion of embedded steel, is extensive, and published literature is replete with case histories indicating that there is a urgent need to develop a better understanding of the corrosion mechanism. The objective of this proposal is to establish a holistic study of corrosion of reinforced concrete. The research will analyze the chemistry of the corrosion mechanism, develop new equipment to determine the degree of distress caused by the corrosion and test the new methodology in field conditions. We will promote an aggressive technology transfer to owners, conctactors and government agencies].
