Abstract

As construction technology advances, most of civil engineering structures are becoming larger and taller. Therefore, high strength concrete is necessary for them. For high strength concrete, it needs a large amount of unit cement content and low water-cement ratio inevitably, so that a large amount of heat occurs in concrete. The thermal cracks make the durability and quality of concrete structures become worse, result from temperature rise and thermal stress due to heat of hydration. In this study, the proposal of using ground granulated blast furnace slag, fly ash and chemical admixtures was investigated to decrease the temperature rise of concrete.
