Experimental Research on the Flexural Strength of Green High Performance Fiber Reinforced Cementitious Composites (GHPFRCC)

Green high performance fiber reinforced cementitious composites (GHPFRCC) is a new class of high performance cement-based composite materials. And it is the optimized mix proportion of Engineered Cementitious Composites (ECC) with high volume fly ash based on the orthogonal experiment method. Emphasis is placed on the flexural strength of GHPFRCC, considering such influences as fly ash content, water-binder ratio, sand-binder ratio, Polyvinyl Alcohol (PVA) fiber and water reducing agent, et al. The results of four-point bending tests indicate that fly ash content has the biggest influence on the flexural strength of GHPFRCC.
