Polypropylene fiber
Percolating-proof short fiber polypropylene fiber grade pp was used as raw material, after the special craft processing and forming of high strength beam organic fiber monofilament, its inherent resistance to strong acid, strong alkali resistance, thermal conductivity, has extremely stable chemical properties. In mortar or concrete can effectively control of mortar and concrete in the stage of the early plastic shrinkage caused by temperature change factors such as micro cracks, prevent and suppress the formation and development of crack, greatly improve the crack resistance of concrete permeability resistance, impact resistance and seismic capacity, can be widely used in underground engineering waterproof, industrial and civil building engineering of roof, wall, floor, pool, basement, and road and bridge engineering. Mortar and concrete engineering cracking, seepage control, a new type of ideal material wear-resisting.

• Main functions:

As the secondary reinforcement of concrete material, the sea can high polypropylene fiber can greatly improve its crack resistance, impermeability, resistance to impact, seismic, antifreeze, anti-abrasion, anti burst resistance, ageing resistance and workability, pumping and water retention.

1. To prevent the cracks of concrete
2. Improve the permeability resistance of concrete
3. Improve the freezing-thawing resisting performance of concrete
4. To improve the impact resistance of concrete, folding resistance, fatigue resistance and seismic performance
5. Improve the durability of the concrete and aging resistance
6. To improve the fire performance of concrete

• Directions for use

1. Recommended dosage:

Ordinary mortar advice each side mortar admixture is as follows: 0.9 ~ 1.2 kg
Suggest adding amount per ton of insulation mortar is: 1 to 3 kg
Concrete advice each side concrete content as follows: 0.6 ~ 1.8 kg (for reference)

1. Construction technology and steps

(1) according to the volume for each of the mixing concrete, according to the requirements of mixture ratio (or suggested dosage) accurately measuring the weight of each join fiber.
(2) application of ready, after adding fiber. Recommend the use of forced mixer. Add the aggregate along with fiber mixer, but must pay attention to should guarantee the fiber between aggregate, dry mix *0 seconds, after adding water, wet mix *0 seconds, make the fiber dispersed adequately.
(3) after the completion of the mixing random sampling, such as fiber has evenly dispersed into monofilament, criterion of concrete can be put into use, if you still have bunch of fiber is extended mixing time of *0 ~ *0 seconds, can be used.
(4) add fiber concrete with normal concrete construction and maintenance process is exactly the same.
