The Properties of High Performance Concrete Using Silica Fume and Expansive Additives

실리카 흄 및 팽창재를 이용한 고성능 콘크리트의 특성

This study is investigate the properties of high performance concrete at W/B of 35%, used with silica fume and CSA expansive additives, which is used to improve the concrete qualities and prevent the drying-shrinkage. According to the results, the fluidity of concrete shows a decline with the increase of replacement percentage of silica fume and proportions of expansive additives. A higher strength is obtained at 5% of replacement percentage of silica fume, while the compensation achieves in drying-shrinkage of concrete at 5% of expansive additives.
