Abstract: The fiber cement mortar was mixed respectively with polyvinyl alcohol fiber, polypropylene fiber, steel fiber and appropriate admixtures in the mortar. By using a jack to take the two-sided shearing experiments of concrete species covered by fiber cement mortar, the study aimed to investigate the influence of fiber types, strength of concrete and strength of fiber cement mortar on the bonding property between concrete and fiber cement mortar. The results of the experiments demonstrated that the shear strength between concrete and polyvinyl alcohol fiber cement mortar was the highest, that of polypropylene fiber took second place, and the shear strength between concrete and steel fiber was the lowest. It was concluded that the higher the compression strength of concrete or compression strength of fiber cement mortar was, the higher the shear strength was. There was a positive linear correlation between shear strength and compression strength of fiber cement mortar. Thus this study, with various types of fibers and a wide range of the fiber strength researched, could provide a theoretical guide for the practical reinforcement engineering.

Key words: concrete compression strength, mortar compression strength, concrete structure reinforcement, fiber cement mortar, interfacial bond property, two-sided shearing
