A field Application of Non-shrinkage High Strength Concrete Using CSA Expansive Additive

CSA 팽창재를 사용한 무수축 고강도 콘크리트 현장적용

Before the field applications, several basic laboratory test were the characteristics of workability and strength of the concrete containing CSA expansive additive. As a result, high strength concrete using CSA expansive additive show similar workability and compressive to that of plain concrete, the optimum replacement ratio of them to plain concrete were obtained for CSA expansive additive 10%. On the other hand, it can be concluded that the use of CSA component is effective to prevent shrinkage crack reducing concrete using superplasticizer and to achive volume stability of concrete structure.
