The Research on Vegetable Fibers as Reinforcement for Cement-based Composites in China and Foreign Countries

The configurations of vegetable fibers that exist widely in the nature have many advantages: great length-diameter ratio,high specific strength,large specific area etc.Fibers play great important roles in restraining the development of concrete cracks.To study and exploit the vegetable fibers as reinforcement of cement-based composites can not only reduce the cost of the concrete but also be helpful to environmental protection and sustainable development.So it is obvious that the significance of investigating the composites is far-forth.This paper summarized the performance of vegetable fiber and its strengthen effect,the research progress of application in concrete as well as the develop prospect and some existing problems.
