Abstract  

A fiber reinforced tailing cementitious composite (FRTCC) was prepared via engineered cementitious composite (ECC) technology. By replacing 50% natural send with tailing sand, the prepared composite presents distinct ductility and environmental friendly-features. The tensile, compressive, flexural and shear ductility of FRTCC as well as the toughening mechanism of polyvinyl alcohol (PVA) fiber were systematically investigated by means of cube compression-, direct tensile-, thin plate bending- and double shear-test. The influence of the content of PVA fiber and the ratio of water to binder on the ductility of FRTCC was examined. The definition of complete toughness ratio was proposed, and the toughness of FRTCC was characterized with a set of double characteristic parameters i.e. the toughness ratio and the toughness index. The results show that the content of PVA fiber and the ratio of water to binder exhibit remarkable synergistic effect on the ductility of FRTCC. The proper mix proportion can significantly improve the ductility and energy absorption capacity of FRTCC, thereby ensure that the FRTCC possesses characteristics such as cracking with multi-cracks, strain hardening and ductile fracture etc.
