Abstract: Polyvinylalcohol (PVA) fiber was created 50 years ago as the first Japanese organic fiber and, it has been used for various applications since then. Especially, PVA fiber has been used globally in a wide range of cement applications since 1980s owing to some suitable characteristics as reinforcing materials for cementitious composites.
At the first, PVA fiber has high tenacity and modulus of elasticity compare with other general organic fiber. Second, bonding strength between fiber and cement matrix is strong. Also it is possible to control bonding strength by surface treatment. At last, good durability has been proved by long terms field test, and it has been used as fiber cement slate over twenty years because PVA fiber has got wide acceptance as a less hazardous and reasonable cost alternative.
In recent years, new type of PVA fiber for high performance fiber reinforced cementitious composites (HPFRCC) has been developed owing to development of theoretical study based on micromechanics. This fiber also starts to use widely because of its suitable characteristics for reinforcing cementitious composites.
