Mortar as construction materials appear in the actual construction process often some drawbacks: brittle, dry shrinkage, low tensile strength, impact resistance and low deformation and poor, so that cracks easily mortar products, thereby reducing the durability of the building sex.
Division I and related research institutes jointly developed a new generation of dedicated organic fibers ---- mortar modified polypropylene (PP) fiber, with a special production process and surface treatment, cross-section was clover (Y) type, excellent mechanical properties , mixed mortar, were evenly distributed to the three-dimensional chaos, highly decentralized, with mortar bond strength is very strong, can prevent, reduce and delay due to creep, plastic shrinkage, syneresis, chemical shrinkage, temperature and load microcracks and other factors, which significantly improves crack resistance, impermeability mortar products, mortar integrity, flexibility, continuity and durability can be improved.
Use Sisiyuan brand polypropylene fibers, no additional special equipment, without changing the composition of the mortar, construction convenient operation, increased cost much, does not pollute the environment, and thus has been widely used in the mortar.
