Polypropylene Fiber

Polypropylene fiber
PROPERTIES:
Our PP fiber monofilament is produced by referring foreign advanced technology for fiber spinning, modified by adding functional additive and special surface-treating. Mixing into cement concrete, it has many advantages such as good dispersing, better water affinity, strong linking force. It is suited to reinforce and crack-resist to every kinds of cement concrete and mortar, specially used in engineering of building surface, floor, wall etc...

APPLICATIONS:

1. Function:
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

2. The Feature of Polypropylene Monofilament:
A). No agglomeration and easily spread around in mortar or concrete. Guarantee the property of crack resistance effectively.
B). Apply conveniently. No need to change the proportion of mortar, and just put the fibers into the mortar mixture and stir for a moment after adding water.
C). Has fine economic property. The equivalent dia. Of polypropylene monofilament is only φ 0.02mm, so the ratio of dia. And surface is high and on the basis of crack resistance, it can reduce the amount (0.6kg/m 3 ) and cut down the cost effectively.
D). Be better to plaster. Because a great number of thin fibers spread into mortar evenly, so the plastering is much easier and this can improve the binding strength between surface and base.
E). The fiber has stable chemical property, strong acid &alkali resistance, and can be used in any engineering projects.

3. Suitable Engineering:
A). Suit for the waterproof layer, floor, inner & outer wall of industrial and civil construction.
B). Increase cracking resistance on the surface of industrial workshop, warehouse and parking lot.
C). Increase cracking & seepage resistance of the ground in natatorium, swimming pool, pond and ditch.
D). Suit for any mortar projects and common concrete projects.
E). Highway, bridge and other roads.

4. Applying Instruction:
A). Dosage: For resist the common cracks on surfaces, 0.9kg/m3 fibers to cement mortar Is enough, and for increasing reinforce and seepage resist application 1.8kg/m3 is enough.
B). 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.
