High Tensile Strength and High Elastic Modulus
Tensile Strength and elastic modulus of PVA fiber are higher than those of another organic fibers. PVA fiber has enough strength to bridge crack of cementitious matrix.
Good Affinity to the Cementitious Matrix
PVA fiber has suitable adhesion to cementitious matrix. Appropriately interaction between fiber and matrix decreases stress localization.
Good Alkaline Resistance
PVA fiber has good alkaline resistance. PVA fiber is hardly damaged by alkaline matrix.
