Popis: In this study, a drop weight testing method was employed to investigate the impact bending behavior of ethylene vinyl acetate (EVA) modified engineered cementitious composite (ECC). The ECC with no EVA was selected as control, and the static and impact bending behavior was compared with the EVA modified ECC. The results showed that the compressive strength of EVA modified ECC decreased by 20%~30% in comparison with control ECC with fly ash substitution ratio variation. The addition of EVA can improve the bending toughness of ECC dramatically under static loading condition. As different from the static bending, the impact bending toughness of EVA modified ECC was smaller than that of control under impact loading condition. However, the degree of damage of EVA modified ECC was lower than control due to small crack width.
