Feasibility of Developing Engineered Cementitious Composite with High Volumes of Fly Ash Using Cost-Effective PVA Fiber

CODEN: JTEVAB

Abstract

In order to reduce the cost of Engineered Cementitious Composite (ECC), a feasibility study of ECC using a Cost-Effective Polyvinyl Alcohol (PVA) fiber (CEPVA-ECC) was developed based on the micromechanical design theory. A set of ECCs with different amounts of fly ash replacement (up to 83 % replacement of cement) was prepared. The CEPVA-ECC using much cheaper Chinese domestic PVA fiber (1/6–1/4 the price of the imported fiber) maintained the tensile ductility characteristics (4–5 %) with a moderate compressive strength (30–40 MPa). The crack width was reduced with an increase of the fly ash amount. The strain map CEPVA-ECC was monitored by the Digital Image Correlation method.
