Macro synthetic fiber Polymacro PM54 has been specifically designed for shotcrete applications and tunnel linings to increase impact and flexural resistance. Homogeneous fiber distribution makes it possible to absorb energy in any point and any direction of the concrete segment; cracking resistance is considerably improved. To increase reliability and service life of concrete linings, our fibers have been designed to increase crack control under high stress and minimize spalling in conjunction points. Synthetic fiber prevents the risk of corrosion compared to steel fiber and wire mesh reinforcement. Due to 0.91 g/cm3 gravity, high number of fibers can be obtained in lower weights. Thus, three-dimensional reinforcement of concrete mix is achieved.
Polymacro PM54 macro synthetic fibers can be used as reinforcement instead of steel mesh and steel fiber within concrete. Polyfibers’ engineering department provides technical assistance on demand for necessary project calculations such as energy (joule) absorption and flexural capacity calculations.
