Polypropylene mesh fiber and fiber can significantly improve the adhesion of mortar and concrete, mortar, concrete progress in the early anti-cracking, hinder useful native cracks concrete mortar attack, bleeding ensure uniformity and avoid tube Segregation hinders settlement cracks constitution. Tests show that 0.1% of the fiber volume content, cracking mortar concrete progress to 70%, together with the significant progress can impermeability to 60% -70%.
Use can significantly improve functionality and wear-resistant concrete impact polypropylene mesh fiber function. Despite the low stiffness of polypropylene fiber, transmission charge to cut the difference, but it can absorb impact energy, useful to reduce the fracture, enhanced media data continuity, reduce some of the stress caused by the appearance of the shock wave is blocked, which can greatly improve the concrete function and impact resistance.
The use of polypropylene mesh fiber can improve the frost resistance of concrete. The effect of participating in polypropylene fibers in concrete, can reduce the temperature changes caused by the internal stress of the concrete, impede expansion temperature cracks; together, concrete frost is also beneficial to the progress of its antifreeze to progress. Internships and seminars are marked participate polypropylene fibers in concrete can be used as a useful way of concrete cracking temperature difference compensation.
The use of polypropylene fiber mesh concrete mortar can improve endurance, significant progress in cutting edge products and the appearance of integrity, and is conducive to internal steel products less susceptible to corrosion. Thus the use of polypropylene mesh fiber are definitely advantages locations.
