This Americas Program award will support Dr. Alberto A. Sagues, of the University of South Florida-Tampa, in a collaborative research program with Dr. Luis A. Maldonado and Pedro Castro Borges, of the Merida Unit of the Center of Research and Advanced Studies of the National Polytechnic Institute (IPN- CINVESTAV), Mexico. Their work will investigate the contamination of concrete by chloride ions from seawater in warm environments, and the effect of that contamination on organically-coated reinforcing steel. The information obtained from this cooperative effort will be critical to the successful control of corrosion in tropical marine environments. The proposed interaction will benefit both nations by establishing a common approach toward corrosion detection and control in a shared geographic region. By increasing our understanding of steel corrosion in concrete, this project has the potential to make a significant contribution towards improving the durability of structures.

该美洲项目奖将支持南佛罗里达大学坦帕分校的阿尔贝托·A·萨格斯博士与路易斯·A·马尔多纳多博士和佩德罗·卡斯特罗·博尔赫斯博士的合作研究项目，墨西哥国家理工学院(IPN-CINVESTAV)研究和高级研究中心梅里达分部。他们的工作将调查温暖环境中海水中氯离子对混凝土的污染，以及这种污染对有机涂层钢筋的影响。从这一合作努力中获得的信息将对成功控制热带海洋环境中的腐蚀至关重要。拟议中的互动将使两国受益，因为它将在共同的地理区域建立一个共同的腐蚀检测和控制方法。通过增加我们对混凝土中钢筋锈蚀的了解，该项目有可能为提高结构的耐久性做出重大贡献。
