Polypropylene Shot Cut Micro Fiber Reinforced Polypropylene Fiber

Polypropylene short cut fiber is made of polypropylene as the main raw material.Its texture is very light and soft.As a concrete reinforced polypropylene fiber,it can increase seepage resistance.Adding polypropylene micro fiber in concrete or mortar can increase impact resistance and peeling resistance.

Polypropylene pp micro fiber has resist to shrink and crack,

Micro PP fiber concrete fiber can prevent mortar split and crackle expansion.

Polypropylene Short Cut Micro Fiber Reinforced Fiber

Polypropylene short cut pp micro fiber is one of the most commonly used polypropylene fiber. Polypropylene short cut micro fiber is a reinforced polypropylene fiber .Polypropylene micro pp fiber is a material used to enhance the performance of concrete, these polypropylene fibers can be evenly dispersed in the concrete to improve the physical properties and chemical stability of concrete. Its length is generally between 1-15mm. Adding these fibers in cement concrete can significantly improve the cracking resistance, durability and working performance of concrete, so improving the safety and serviceability of concrete.

Instructions for the use of polypropylene pp micro fiber concrete fiber :

1、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.

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

3、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,striring by adding water at worksite before constructing.
