Abstract：
There are various natural green raw fibers and they could guarantee favorable interface bonding property between cement and fiber as long as their surface is pretreated properly, such as being soaked in chemical agent or being coated by polymer to "block" cell cavity and micro-capillary porosity. However, there are several critical problems, such as how to realize better surface modification of existing raw fibers and how to solve fiber aggregation due to large addition of fiber, etc. It was proposed to develop new compound chemical auxiliary agent and coating agent, to use the best compound fiber treatment technique and to increase the addition of fiber. Great significance was provided for effective utilization of processing residual and agricultural wastes.
