Evaluation of durability of an ECC(Engineered Cementitious Composite) designed with ground granulated blast furnace slag

고로슬래그 미분말이 혼입된 ECC(Engineered Cementitious Composite)의 내구성 평가

This paper presents the experimental results for durability of an ECC designed with ground granulated blast furnace slag (BFS) through the test method of chloride ion resistance and freezing-thawing resistance. In order to compare with ECC, normal mortar was also tested. Test results showed that BFS ECC exhibited higher durability performance than ordinary mortar. These results suggest that by adding BFS in ECC, its matrix density is increased which results in decreased of deterioration and it also adds to the fiber bridging that contributes in control of cracking.
