| Abstract: | This paper summarizes the advances of current researches of Polyvinyl Alcohol-Engineered Cementitious Composite (PVA-ECC).The concept of related properties of ECC are introduced briefly.The current theoretical research of PVA-ECC,ultimate ductile property and the strain-hardening behavior,the micromechanism and the concept of Integrated Structure and Materials Design are especially introduced.The experimental of PVA-ECC,such as the interface properties,the flexure tests,tensile-compression cyclic test ,shear tests are reviewed.Some problems that need to research in the future are suggested. |
