Abstract

Many researches have been carried out on development of high-strength concrete, but most researches have been focused on building structures such as a high-rise building. However today, the demand of high-strength concrete for civil structures like a PSC bridge is increasing steadily. In addition, the current design code based on experimental results of normal strength concrete needs to be modified for high-strength concrete structures. Therefore, it is necessary to perform a research on mechanical properties and mix proportion of high-strength concrete suitable for PSC bridges. The primary purpose of this study was to develop the high-strength concrete mixtures which can be applied to PSC bridges and to evaluate mechanical properties of high-strength concrete.
