POLYAMIDE FIBER FOR REINFORCING CONCRETE

摘要

Polyamide fiber for excellent reinforcing concrete is provided to offer excellent dispersibility within the concrete and cohesive property and to widen contact areas with concrete. Polyamide fiber(F) for excellent reinforcing concrete has protrusion parts of 3~16 on a section of fiber. Relative viscosity of polyamide fiber is 2.9 or greater. Intensity of the polyamide fiber measured by gauge length is 7.5g/d or greater. Elongation of the polyamide fiber measured by gauge length of 5 mm is 50~120%. Length of the polyamide fiber is 12~25mm.
