Abstract
Quasi-static compressive strength and dynamic impact compressive response of PVA fiber reinforced cement-based composite (PVA-FRCC) with different water binder ratio were studied. The quasi-static compressive strength decreased with increasing water binder ratio. The split Hopkinson pressure bar (SHPB) was used to obtain the dynamic impact compressive response of PVA-FRCC. The results showed that the stress-strain relationship of PVA-FRCC with different water binder ratio performed obvious strain rate effect. The deformation capacity of PVA- FRCC under dynamic load was improved with the increase of water binder ratio. The energy absorption capacity also performed rate dependency; as water binder ratio increase, the energy absorption capacity of PVA-FRCC was weakened.
