초록

In the construction industry concrete materials has that exhibits the advantage of a high compressive strength at an affordable price, beside it has that present a disadvantage of brittle fracture such as not withstand the low impact on the tensile strength. Recently there is the impact safety concerns of building by terrorism and explosions are treated heavily. The way to correspond the high-performance fiber-reinforced cementitious composites(HPFRCC) has been emerging as an important measure. However the existing research of HPFRCC was about a single type of fiber as it has an advantage such as convenience in placing depend using one kind of fiber, but it also has a disadvantage of fluidity, sensitivity and toughness etc. in quality rather than using 2or more composite fiber mixture. In this study, HPFRCC consist of 3 species of the SL+SS+OL fibers combination to research analysis of various engineering characteristics in variable terms of fluidity, tensile strength etc. of W/B and fiber replacement ratio to suggest the best mixing ratio which can be used in partical. As a result in the case of a 3 species fiber combination of SL+SS+OL reviewed engineering characteristics of workability, compressive strength and tensile performance etc. the best result was when W/B is 25% with 2.0%of fiber combination replacement ratio.
