Abstract

In the present study, we have developed high strength concrete which is adequate for the long span PC beam above 40 meters. We have selected the most adequate materials for high strength concrete through laboratory tests and in-situ mock-up applications. We verified and decided the best curing condition of high strength concrete, and suggests the optimum mix design of high strength concrete. In the future, we will verify the properties-fresh and hardened concrete- of high strength concrete and its serviceability, and also apply the high strength concrete to newly-constructed real bridge structure.
