ECOFIBER-PP polypropylene monofilament micro fiber – ANTI-FRACTURE

ECOFIBER-PP is a new generation of polypropylene microfiber for concrete reinforcement, which combines the ultra-fine fiber diameter with high strength. Due to the tens of millions of ECOFIBER-PP filaments existing in a cubic meter of concrete, an extremely dense three-dimensional entanglement is created. This interlacing of these very strong filaments eliminate the occurrence of cracks at the microscopic level.
The function of ECOFIBER-PP is not to replace steel, but avoid micro cracks thus obtaining a concrete with a much better, more stable surface and more resistant concrete which increases the lifetime of the concrete – particularly when it is exposed to adverse weather conditions.

The ability of ECOFIBER-PP (with it’s 550 million filaments per kilo ) to reduce cracking in the first 24 hours after placing of concrete and mortar is so significant that the recommended dosage is much lower when compared to other polypropylene fibers used in the market . Recomended dosage for ECOFIBER-PP per m³ of concrete is 300gr. whereas other fibers recommend 600grs..
