홈페이지논문 초록 (Abstract)
??In comparison with the current plain cementitous composites, DFRCC (Ductile Fiber-Reinforced Cementitious Composites) have a big merit of toughness improvement effect. The improvement has a crucial role in securing reinforcement effect which is obtained through mixing fibers and conducting precise measurement of toughness. ??In order to define and evaluate the type of fine sand and its effect on hybrid, this study examined the hybrid derived from a mix of PVA fiber (39, 100㎛) having different mixing contents with cementitous composites having water-binder ratio of 23% and assessed the fluidity, toughness and bending behavior of DFRCC mixed with fine sand having different cement volume ratio of 4, 7.5 and 10%. The result of the study shows that PP fiber was light-weighted, deformation capacity was improved and compressive strength of PS and NS was enhanced to some extent, but the level of bending strength was almost same. Bigger macro fiber with large diameter in the same fiber contents had increase in fluidity but decrease in bending and deformation capacity and toughness index, according to the result.
