iPREFS. Fibers for precast products.
The fibers iprefs are indicated in the embodiments of prefabricated components such as: manholes, curbs, panels, tanks, gutters, tile drains, covers, railroad crossings, precast plates for rails and more, in general, all items which require a reduction or substitution of metallic reinforcements.
The substitution of metallic reinforcements permits to:
iPREFS fibers, in contrast to normal metallic reinforcements (mesh or fiber), do not corrode, do not create magnetic impedance, are resistant to acids, base elements and generally all aggressive substances, since they are chemically inert. Concrete reinforced with iPREFS fibers has increased durability and mechanical and shock resistance.
Dosages can vary from 1.5 to 5 kg/m3 according to the type of performance required in the fiber reinforced concrete.
They are available in three different sizes (29/39/49 mm) according to the type of application being used and the thickness of the underlayment.
They can be inserted on the aggregates conveyor belt at the mixing plant or directly in the concrete mixer at the start of the cycle or with packaged concrete mix as the final ingredient. iPREFS fibers disperse evenly into the concrete mixture, do not create sediment, nesting or lumps, even in larger doses.
