Experimental Study on Mechanical Properties of PVA Fiber Reinforced Tailings Cementitious Composites

Abstract:

A type of ecological engineered cementitious composites, which use iron ore tailings to replace fine grinding quartz sand in PVA fiber reinforced cementitious composites, was developed. The flexural strength and toughness of this material were studied by four-point flexural test with samples of beam and sheet. The results show that the fiber reinforced tailings cementitious composites exhibit the characteristics of multiple cracking, high ductility and flexural toughness. The studies indicate that the mix proportion and the fiber length have a significant influence on the properties of this material, particularly for tensile toughness.
