The use of pp fibers or polypropylene fibers increases the bending strength, tensile strength, shear and abrasion. PP fibers are used as concrete additives to reinforce and reinforce concrete and cement and gypsum mixtures.
Polypropylene fibers, when mixed with concrete, do not dissolve and increase the weight of the concrete and eliminate the alkaline environment of the concrete.PP fibers with two 12 and 18 mm cuts are used for concrete and 6 mm long cutting for use in thin plaster mortars.
