Description
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.

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.
- To prevent the cracks of concrete
- Improve the permeability resistance of concrete
- Improve the freezing-thawing resisting performance of
concrete
- To improve the impact resistance of concrete, folding
resistance, fatigue resistance and seismic performance
- Improve the durability of the concrete and aging
resistance
- To improve the fire performance of concrete
- 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)
- 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.
