Abstract: The common concrete have many advantages, but its brittleness, easy to produce craze, the diffusion speed of chemical substances increase from outside to internal, the service life of structures was shorten.Joining the polyvinyl alcohol fiber is an effective way to solve this problem.Paper introduces the polyvinyl alcohol fiber reinforced cementitious composites research status at home and abroad, the dynamics characteristics and self-healing situation, discussing the micro design theory of the material, introducing its application, and the research of polyvinyl alcohol fiber reinforced cementitious composites is prospected.
