Spite of the several advantages of durability and economic characteristics, such as civil engineering and construction materials, which is widely used as a mortar and concrete, and the tensile strength of fragility and brittleness due to local damage caused. This mechanical shortcoming ensure ductility and brittle complement the various fibers used in concrete and mortar has been developed in order to improve the energy absorption capacity, and increase the use of multiple structures in the form of.Now widely used in the polypropylene fiber polypropylene and affordable, excellent chemical stability and durability, but mainly use the nature of water and mix well so the fluorinated surface hydrophilic polypropylene fibers that can be granted through the processing unit,to overcome this.
