| Abstract: | Surface treating methods were conducted on PP fiber to improve the PP fiber cement interface bonding strength. Acid, alkaline surface treating were employed. Effects of surface treatment were investigated. The experiment result shows that the acid, alkaline treatment will increase the surface coarseness of PP fiber, and the PP fiber cement bonding strength will improve. Also, notable reductions of plastic shrinkage cracking in PP fiber cement mortar were observed. It was concluded that surface treatment of PP fiber with acid, alkaline improved the PP fiber cement bonding strength and reduced plastic shrinkage cracking in PP fiber cement mortar. |

| Keywords: | PP fiber interface bonding strength anti shrinkage performance |
