碩士 === 國立成功大學 === 土木工程研究所 === 85 === ABSTRACT The depth of cover to the steel in reinforced concrete is closely connected with the cracks occured in it, and this relationship could be regarded as a major factor in probing the durability of reinforced concrete. As to the fields of materials, mechanics, management, mix design and construction are evenly very important. High Performance Concrete has been developed for some time and now had been put to work practically in special engineering projects. Even though at this time, there is no specific method in determining the proper depth of cover for engineering use. First of all, the prevailing covering of reinforced concrete used in common structure and their corresponding results of cracks were collected and used as basic data. After analysing and evaluating the basic data carefully with the reliable design, then the determining method could be found. From this study, it was recognized a relationship of square root between Carbonation depth OF High Performance Concrete and Time is gradual. This could be used as one of useful information to our concrete engineering. Lastly many parameters used in this paper were still required to do further research to obtain more useful data base.
