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.
