Abstract

This paper is to investigate the strength, impact endurance and shrinkage of wet spraying type fiber composite mortar for repair material depending on fiber type and product kinds. Fiber composite mortar containing PVA fiber had the highest strength compared to that using any other fiber. Especially, The use of PVA fiber results in a remarkable enhancement in impact strength and an improved volumetric stability. Accordingly, it is confirmed that fiber composite mortar containing PVA fiber has remarkable performance as repair material of damaged section of concrete.
