PET 섬유를 사용한 시멘트 복합체의 역학적 특성에 관한 연구

In this paper, workability, compressive strength of hybrid fiber reinforced cement composites(HFRCCs) have been investigated by means of Korean Standard Testing Methods (KSTM). Hybrid fiber reinforced cement composites(HFRCCs) contains the polyethylene terephthalate(PET), polyethylene (PE), and polyvinyl alcohol (PVA) fiber. As the result of the compressive strength tests, all the specimens show multiple cracking in the area subjected to the greatest compressive stress. In particular, test results showed that the hybrid fibers, PE and PVA specimen, could result in superior composite performance compared to their individual fiber reinforced cement composites, PET specimen.
