A Study of Properties of Drying Shrinkage and Creep of Concrete Incorporating Hwangtoh and Blast Furnace Slag

황토와 고로슬래그를 첨가한 콘크리트의 건조수축 및 크리프 특성에 관한 연구

The objective of this experimental study was to understand inelastic strain of concrete incorporating hwangtoh or combination of hwangtoh and slag. Main variables were replacement level of admixtures, hwangtoh and slag. We studied the properties of concrete such as heat of hydration, drying shrinkage and creep according to the replacement level of hwangtoh and slag. Test results showed that the heat of hydration of concrete decrease with increasing hwangtoh and slag replacement. Also drying shrinkage and creep of concrete increase with increasing hwangtoh replacement.
