PVA engineered cementitious composites （PVA-ECC） is a cement-based composite materials made of cement，
mineral admixture，water，fine aggregate particle size less than 5 mm mixing with PVA fiber. This paper summarizes the basic
performance of PVA-ECC. Compared with general concrete，the capacity after the peak load test decreased slowly in the
compression，and tensile and bending tests show strain hardening characteristics，and it has better shear strength shear
deformation. ECC have excellent ductility and durability, and it has been successfully applied in practical engineering.
