PP fiber


PP fiber is a polypropylene as the main raw material, adopting unique manufacturing process to make high strength bundle monofilament fiber. Join concrete (or mortar) can effectively control concrete (or mortar) micro-cracks which is caused by plastic shrinkage, temperature changes and other factors, to prevent and inhibit the formation and development of cracks, greatly improved crack resistance of concrete, impact resistance and seismic capacity

Main Application

Resist to shrink & crack *Increase seepage resistance *Increase friction resistance *Increase freezing & thawing resistance *Improve tendons protection *Replace steel net (using in plastering) * Prevent mortar split and crackle expansion *Increase impact resistance and peeling resistance


For resist the common cracks on surfaces, 0.9kg/m3 fibers to cement mortari is enough. For increasing reinforce and seepage resist application 1.8kg/m3 is enough

Stirring requirement

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 with cement and other aggregates in advance, stirring by adding water at worksite before construction.
