Abstract: Polyvinyl Alcohol (PVA) fiber reinforced engineered cementitious composites (ECC) is a kind of composites reinforced with moderate fiber volume fraction, typically 2% by volume.
Of special interest is the capability of ECC material to deform to high tensile strains, commonly over 4%, while maintaining very tight crack widths. The standard ECC mix proportion is widely available in the literature; nevertheless direct adoption of such mixture cannot guarantee high tensile ductility due to wide material variations geographically.
Furthermore, to reduce the material cost, domestic PVA fibers must be utilized, which has different physical/mechanical properties compared with commonly used PVA fibers from Japan. In this paper, Chinese domestic PVA fibers were adopted to develop highly ductile ECC material, along with other local ingredients, such as fly ash, cement and sand.
Preliminary results from flexural test suggest it was feasible to use local ingredients to produce ECC material in order to reduce material cost, promoting the use of this material in civil engineering fields in China.
