MASTERFIBER 246 SPA

Synthetic macro-fibers for fiber-reinforced concrete, damp earth, screeds for heated floors, concrete floors, in water-soluble pods.

MasterFiber 246 SPA is a synthetic macro-fiber obtained by extrusion of synthetic polymers based on polypropylene, with a “wavy” profile, optimized to increase adhesion to the cement matrix of the conglomerate. It allows to reinforce the concrete, increasing its ductility and toughness.

The use of MasterFiber 246 SPA synthetic macrofibers are particularly indicated in the packaging of conglomerates intended for alkaline environments, where high chemical resistance is required, in aggressive or potentially aggressive environments, in all cement-based systems where a corrosion. To facilitate dosing, the MasterFiber 246 SPAs are packaged in 65 gr pods. in water-soluble film. The MasterFiber 246 SPA synthetic macro-fibers have a good dispersibility within the cement mixtures, an essential element for the production of homogeneous concretes. MasterFiber 246 SPA is recommended for the realization of:

• • prefabricated elements for shed roofing;
  • prefabricated panels with thermal break or lightened;
  • earthy-damp concrete products;
  • screeds for heated floors in partial or total replacement of continuous type reinforcements;
  • concrete slabs for aesthetic and industrial flooring.

The use of MasterFiber 246 polymeric macrofibers SPA can take place in complete or partial replacement of the primary armor. In this case, please note that FRC, structural fiber reinforced concrete must be compliant with what is reported in the DM. 17/01/2018 (Standards
Construction techniques) and Circular no. 7/2019. MasterFiber 246 SPA can also be used in place of the distribution reinforcement (electrowelded mesh) for counteract thermo-hygrometric movements.
