Fiber Reinforced Cementitious Composites

Green high performance fiber reinforced cementitious composites (GHPFRCC) is the optimized mix proportion of engineered cementitious composites (ECC) with high volume of fly ash and polyvinyl alcohol (PVA) fiber. To study the compressive performance, the prism stress-strain relationship of GHPFRCC is the focus in this study. There are sixteen groups of GHPFRCC specimens with the size 40mm×40mm×160mm. The compressive stress-strain curves were obtained based on the uniaxial compression tests. Experimental results show that the uniaxial compression stress-strain curve belongs to the skewed unimodal curve. The peak strain can steadily reach more than 0.005, and it has put up a great plastic deformation capacity and post-peak ductility. It has still reserved some residual strength even when the strain is up to a bigger value. The research achievements can promote the application of GHPFRCC in the practical engineering.

Slump Flow

ABSTRACTThis paper investigates the compressive strength and workability of High-Performance Concrete (HPC) which yields a slump at 250 ± 20mm and a slump flow at 650 ± 50mm. From the complete stress-strain curve, it shows the peak strain will be higher while the strength increases. Two kinds of the post failure models can be distinguished. The first type (Type I) is called strain softening and the second type (Type II) is called strain snapping back. Also, it is found that the modulus of elasticityEcdecreases as the volume of cementitious pasteVpincreases. On the other hand, Poisson's ratio ν increases asVpincreases.
