Abstract

As construction technology advances, most of concrete structures are becoming larger and taller. Therefore, high strength and high quality concrete is necessary for them. Nowadays, the proposal of using type IV(belite cement) is investigated to satisfy high flowing, low heat, and ho호 strength. In this study, the flow value and compressive strength of mortar were investigated according to usage of AE high range water reducer. And the slump flow value, falling time and heigth difference of concrete with beilte cement and ordinary cement were examined depending on water cement ratio, sand ratio and unit water weigth, and compressive strength to checked depending on age.
