Durable Polypropylene Micro Fiber for Concrete Works
Durable polypropylene micro fibers for concrete works are made from high-quality polypropylene as the raw material, through special melt spinning and surface treatment processes. They are high-quality modified materials that enhance the durability and construction performance of concrete. This polypropylene micro fiber is lightweight, with a density of only 0.91-0.93 g/cm³, and has stable chemical properties, with extremely strong acid and alkali resistance. It can resist various chemical medium erosion, does not age or rust, and can maintain stable performance in the concrete interior for a long time, meeting the long-term durability requirements of the project.

Durable polypropylene micro fiber main advantages:
The durable polypropylene micro fibers are high modulus pp monofilament fibers.The core advantage lies in its excellent dispersibility. During mixing, the pp micro fiber does not easily form lumps and can form a uniform three-dimensional supporting network in the concrete, effectively inhibiting the occurrence of plastic shrinkage cracks and drying shrinkage cracks, reducing surface dusting and peeling phenomena. At the same time, it does not need to change the original concrete ratio, the construction is convenient, and can significantly improve the impact resistance, wear resistance and water resistance of the concrete, and reduce the risk of water and harmful substances penetration.

PP micro fiber for concrete feature:
◆Excellent 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.


PP microfiber reinforced 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 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.


Durable 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.
Durable polypropylene micro fiber is widely used in the roofs, floors, interior and exterior walls of industrial and civil buildings, as well as in various projects such as factories, parking lots, pools, roads, etc. It can be adapted to various masonry and fine aggregate concrete projects. It can not only ensure the quality of the concrete surface but also extend the service life of the project. It is both economical and practical, and is an ideal material for enhancing crack resistance and improving durability in concrete projects.
