UV Stabilized PP Micro Fiber for Concrete Reinforcement

UV Stabilized PP Micro Fiber for Concrete Reinforcement

UV stabilized pp micro fiber for concrete reinforcement is a high performance concrete fiber.As concrete grade PP monofilament fiber, it has excellent mechanical properties and chemical stability. Its tensile strength is not less than 450 MPa. It is resistant to acid, alkali, freeze-thaw, and is suitable for various projects. After being added, the polypropylene micro fiber Concrete formed can significantly inhibit plastic and drying shrinkage cracks, and simultaneously enhance impermeability, impact resistance and wear resistance. The ultraviolet stability formula can resist long-term outdoor exposure, avoid aging and degradation, and is suitable for outdoor scenarios such as bridges and roads.

Concrete reinforcement Polypropylene micro fiber  feature and advantages:

◆Easy dispersion and simple construction

The fibers of the special additive for polypropylene micro fiber for construction are processed through a unique technology, which gives them excellent dispersion. During the concrete mixing process, they can quickly and evenly disperse throughout the concrete system, avoiding fiber agglomeration and ensuring that every part of the concrete is effectively reinforced, thereby enhancing the overall performance of the concrete.

◆Chemical corrosion resistance

Polypropylene micro fibers maintain stable physical and chemical properties in both acidic and alkaline environments as well as in media containing various chemical substances. They do not react chemically with other components in the concrete, thus ensuring the long-term durability of the concrete structure.

◆Flexibility and high strength

The polypropylene fiber mortar fibers have good flexibility and can form a three-dimensional random network structure within the concrete or mortar. At the same time, they themselves have high strength, which can effectively disperse stress when the concrete is subjected to external forces, enhancing the toughness of the concrete.

◆Strong anti-aging performance

Polypropylene fibers have excellent resistance to ultraviolet rays and oxidation. Even when exposed to outdoor environments for long periods, they are not prone to aging or degradation, and can continuously provide reinforcing protection for the concrete, extending the service life of the concrete structure.

◆Widely application

Suitable for various types of concrete and mortar, including ready-mixed concrete, precast concrete, self-compacting concrete and sprayed concrete. It is an ideal reinforcing material for civil engineering and has no adverse effects on the setting time and strength development of concrete.

Polypropylene microfiber reinforced concrete fiber function:

◆Adding reinforced polypropylene microfibers to concrete can suppress early cracks.

◆The use of concrete reinforcing fibers can reduce bleeding and segregation during concrete pouring, and improve surface flatness.

◆Polypropylene reinforced fiber concrete can also slow down the carbonation rate and chloride ion penetration rate, delay the corrosion of steel bars (if the structure contains steel bars), and extend the maintenance cycle.

◆The application of polypropylene fibers expands the application scenarios of concrete, enabling ordinary concrete to be used in areas with higher requirements for toughness and crack resistance, such as precast wall panels (reducing cracking due to insufficient thickness), shotcrete, and repair projects, where it can enhance the bond strength at the interface between new and old concrete and prevent cracking and peeling during repairs.

Applying instruction of pp micro fiber concrete fiber :

◆Length of polypropylene  pp monofilament fiber:

Fine aggregate concrete such as mortar is suitable for polypropylene micro fiber length less than 12mm, and coarse aggregate concrete is suitable for concrete above 12mm.

◆Compounding Amount:for resisting the common cracks on surface,0.9kg/m ³fibers to cement mortar are enough.

◆Ratio and mixing requirements:the proportion of cement,sand and aggregate is no need to be changed.Put cement,aggregate,additive and fiber together,then stir after adding enough water and time for stirring can be prolonged for 2-3 minutes in order to make the compound mix completely.Also it can be mixed even with cement and other aggregates in advance,stirring by adding water at worksite before constructing.

Anti-crack polypropylene monofilament fiber can control the development of microcracks

Practical cases of polypropylene PP micro fiber:

◆A certain expressway pavement was doped with 0.9 kg/m³ PP monofilament fibers, reducing the crack incidence rate by 60% and extending the service life by 8 to 10 years

◆The industrial floor uses PP fiber concrete, which enhances its resistance to sulfate erosion by three times and extends the maintenance cycle from two years to six years

 PP Microfibers applications:

◆polypropylene micro fiber is suitable for the water-proof layer, floor, inner & outer wall of industrial and civil construction.

◆Polypropylene fiber is used for surface cracking resistance and enhancement treatment of  industrial workshop, warehouse and parking lot.

◆Increase cracking & seepage resistance of the ground in natatorium, swimming pool, pond and ditch.

◆Polypropylene micro pp fiber is suitable for any mortar projects and fine aggregate concrete projects.

◆Prefabricated components and prefabricated buildings.
