توضیحات محصول
High strength concrete additives para-aramid yarn polypropylene staple fiber pp fiber staple virgin fiber
high strength concrete additives
Brand: Polyfiber
Raw material: 100 polypropylene
Diameter: 15~40micro\
Fineness: 2.5~15 denier

Ⅰ.Prevent the cracks in the concrete and used in cement roads, bridges, airports, floor and so on.
Ⅱ.Improve the penetration resistance of the concrete, like the tunnel walls, coal factory,house roofs, reservoirs, rivers, dams, etc.
Ⅲ.Improve the freeze-thaw resistance performance.of the concrete.
IV.Improve the performance of the impact, bending, fatigue, seismic of the concrete., like the military engineering of the civil defense, oil drilling platforms.
V. Improve the durability, aging resistance of the concrete.
VI.Improve the fire resistance of the concrete, like chimneys, refractories.materials.etc.
