6mm Polypropylene Microfiber 12mm Polypropylene Microfiber 19mm PP Micro Fiber for Concrete
3-19mmPolypropylene monofilament reinforced concrete fiber function:
◆3-4mm short pp monofilament fiber ultra-fine distribution, excellent surface anti-cracking, won’t expose on material surface,be mainly used for Wall plaster, cement putty, tile adhesive, thin-layer mortar, interior & exterior wall coatings.


◆6mm PP micro fiber is the most popular universal length.it Balanced performance of anti-crack and reinforcement, good mixing & dispersion.it used for Common cement mortar, small precast parts, floor screed, general concrete products.

8-10mm length polypropylene micro fibers has higher toughness, stronger resistance to shrinkage and impact.It used be Ordinary cast-in-place concrete, industrial floors, parking lots, sidewalks, curb stones.


12-19mm pp monofilament fiber has highest tensile connection effect, outstanding anti-fatigue and anti-deformation performance.It used be Road pavement, bridge deck, tunnel lining, shotcrete, hydraulic engineering and Reinforce thick concrete structures, prevent deep and penetrating cracks under heavy load.


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
