균열 자기치유형 혼화재 적용 콘크리트의 수축균열 평가
Evaluation on the shrinkage crack of concrete with crack self-healing agent
- 발행 : 2014.05.29
초록
Concrete with self-healing admixture can reduce the crack width by using a compound for chemical reaction with incoming water and carbon dioxide through the crack. Also, concrete with self-healing admixtures can reduce early-age shrinkage crack by using a inorganic expansive agent. In this research, we perform the basic workability test and compressive test. Also, We measure the drying shrinkage of concrete specimen. Finally, we make mock-up (3m X 3m X 0.23m) and monitor the crack width and length for 3 months.
