The main roles of fiber in mortar are crack resistance, toughening, impact resistance, permeability resistance, frost resistance and fatigue resistance, etc.
① Crack Resistance: Prevent the extension of original defect cracks in the mortar matrix, effectively prevent and delay the emergence of new cracks;
② Permeability Resistance: Improve the density of mortar matrix, prevent the invasion of external moisture, and improve the water resistance and permeability resistance of mortar;
③ Durability: Improve the frost resistance and fatigue resistance of mortar matrix, and enhance durability.
④ Impact Resistance: Improve the rigidity of mortar matrix, increase toughness, reduce brittleness, improve the deformation capacity and impact resistance.
