Polypropylene fibers to prevent micro cracks in concrete
PP fibers are used in concrete to obtain a much better, more stable surface and more resistant piece of concrete. It reduces the danger of micro cracks dramatically. This increases the lifetime of this piece of concrete – especially true where this is exposed to changing weather conditions ; The PP fibers should be mixed with the concrete only after the concrete is produced and …">
