Fundamental Study of Nonshrinkage High Strength Concrete using Calcium Sulphoaluminate Cement

칼슘설포알루미네이트 시멘트를 이용한 무수축 고강도콘크리트의 기초적 특성연구

In this study, the fundamental properties of nonshrinkage high strength concrete using calcium sulphoaluminate cement (CSA cement) which was develiped at the Ssangyong Cement Ind, CO., Ltd. Were considered by some experiments. The concrete using CSA cement show a good workability and higher strength development in early age. And, the resultant compressive strength was also higher than OPC. The drying shrinkage of CSA concrete was much less than that of concrete made with OPC and expansive agent.In addition, the value of drying shrinkage was not dependent on the agitating time and the curing condition. Compared to that of OPC.
