Reinforced Polypropylene PP Monofilament Fiber

Reinforced Polypropylene PP Monofilament Fiber 

Polypropylene monofilament fiber(pp micro fiber) is a kind of high-strength bundle fiber. When monofilament fiber is added to cement or concrete, it can be evenly dispersed in the concrete to improve the physical properties and chemical stability of the concrete. It can significantly enhance the fracture toughness and durability of concrete, as well as its impact resistance. Highly resistant to chemical substances such as acids, bases and salts. It is suitable for corrosive environments such as chemical plant floors and Marine engineering.

Polypropylene monofilament fiber concrete fiber parameters:

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.

Key points for the construction of monofilament fibers(pp micro fiber)：

◆Uniformity of dispersion

Dry-mixing method: First, dry-mix the pp micro fibers with aggregates and cement, then add water and stir (extend the time by 15 to 30 seconds).

Wet mixing method: Concrete fibers are slowly added to the already mixed concrete to prevent clumping.

◆Mix ratio adjustment

Appropriately increase the dosage of water reducing agent to compensate for the decrease in fluidity caused by the addition of fibers.

◆Maintenance requirements:

Just like ordinary concrete, it is necessary to ensure adequate wet curing to prevent early cracking.

Practical cases of reinforced 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

Application with polypropylene fiber concrete martor fiber:

◆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.
