The Study on Long-Terms Properties of Concrete Using C Class Fly Ash

C급 플라이애쉬 콘크리트의 장기특성에 관한 연구

The primary purpose of this study is to investigate reusal techniques of by-product produced the combined heat power plant in the construction field, which may contribute to the savings of construction materials and the conservation of enviornment. This study is compared and evaluated by testing the chemical resistance, adiabatic temperature rising test, creep and drying shrinkage. As the result of the study, the following conclusions are derived : (1) hydration heat of the fly ash concrete is less than the plain concrete in adiabatic temperature rising test, (2) the fly axh concrete (FA 30%) is similar to the plain concrete in the chemical resistamce, (3) the fly ash concrete (FA 10, 30%) is similar to the plain concrete in drying shrinkage, but the fly ash concrete (FA 50%) is highly increased, (4) the fly ash concrete (FA 30%) is less than the plain concrete in creep test.
