Why is Belmix available in different cut lengths?

Based on the different recipes for concrete (for flooring and precast elements) and mortar (for screeds and external wall coatings), BELMIX fibers are available in various cut lengths according to the grading curve of the building material. This will preserve a perfect homogeneity of the mixture and guarantee optimal resistance of the building material in its green age (first 3 to 4 hours).
