YL-PMF POLYPROPYLENE MACRO FIBER
YL-PMF POLYPROPYLENE MACRO FIBER
GB/T21120-2018 Synthetic fibres for cement concrete and mortar
Description
YL-PMF uses 100% polypropylene as raw material and is manufactured through a special process. It is a concrete reinforcement fiber dedicated to highways, railways, tunnels, culverts, etc.
Performance
●It has the characteristics of stability at high temperature, crack resistance at low temperature, fatigue durability, shrinkage resistance and good ductility;
●Good workability and dispersion, simple and safe operation;
●High strength, corrosion resistance, acid and alkali resistance, aging resistance and rust resistance;
●The embossed surface greatly improves the cohesive force between fiber and concrete, and also increase shrinkage resistance and crack resistance.
Application
●Cement products, such as precast concrete panel and component;
●Concrete road, pavement, bridge deck, airfield runway;
●Port, sea terminal, highway;
●Basement wall, slab dam in hydraulic project and hydroelectric project;
●Shotcrete, and concrete project, like being used in base, ground, bridge, dam, especially where relatively large-scale deformations may be expected, such as in tunnel lining and mining engineering environment.
