An Experimental Study on the preparation of High Performance Concrete

고유동콘크리트의 제조에 관한 실험적 연구

The aim of this study is to develop High Performance Concrete, which can fill in every corner of forms without using any vibrators. In order to place concrete into reinforced members, concrete should have segregation resistance and high flowability. In this study, the binder of concrete, such as Ordinary Portland Cement, fly ash, and blast furnace slag, cement were mixed with the addition of superplasticizers and tested their flowability and segregation resistance using slump flow tester and L type flow tester. As a results, High Performance Concrete can be made using Portland blast furnace slag cement along with superplasticizers but the slump-loss of concrete is so large that measure should be made.
