Fiber polypropylene glass fiber is 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.Add to the concrete or mortar can effectively control the concrete (mortar) solid plastic shrinkage, drying shrinkage, temperature change caused by 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, etc., as well as in road and bridge engineering.Is the mortar/concrete engineering cracking, seepage prevention, wear-resisting, heat preservation of new ideal materials.

Security: non-toxic, no stimulation
Low temperature sex: no change the - 78 ℃ experiments to measure performance, non-magnetic
Packing: 0.9 kg/bag, 18 kg/bag (customizable)
Main functions: as the secondary reinforcement of concrete material, HDF - PP 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.
S to prevent the cracks of concrete
S to improve the permeability resistance of concrete
S improving freezing-thawing resisting performance of concrete
S to improve the impact resistance of concrete, folding resistance, fatigue resistance and seismic performance
S to improve the durability of concrete, aging resistance
S fireproof property of the concrete
Areas of application:
Water resources and hydropower engineering, and cast-in-situ concrete prefabricated, municipal, roads, Bridges, housing projects, industrial production the pre-mixed mortar, etc.
Recommended dosage:
Mortar advice each side mortar admixture is as follows: 0.9-0.9 kg
Concrete advice each side concrete content as follows: 0.6-1.8 kg (for reference)
Construction technology: fiber itself as the inert materials with concrete aggregate, admixture, admixture and cement will not have any chemical reaction, fiber adding without changing the original concrete mixture ratio, no special requirements for various performance index of the aggregate.Construction, according to the proportion of directly to the fiber into the blender.No special requirements to mixing and construction technology, as long as appropriate to ensure mixing time can be used.Using steps are as follows:
1, according to the volume for each of the mixing concrete, in accordance with the requirements for mixture ratio (or suggested dosage) correct measuring the weight of each join fiber.
2, after the application of ready, adding fiber.Recommend the use of forced mixer.
3, add the aggregate along with fiber mixer, but must pay attention to should guarantee the fiber between aggregate, dry mix 30 seconds, cement and water, wet mix 30 seconds, make the fiber dispersed adequately.
4, 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 20-30 seconds, can be used.
5, add fiber concrete with normal concrete construction and maintenance process is exactly the same.
Note:
1. Head of fiber only as "secondary reinforcement of concrete, rather than the structure reinforcement, so the head of the fiber mixed with the reinforcement ratio does not change the original design.
2. Head of fiber can't replace the structural strengthening material, can't separate for settlement and the strong force of impact crack, cannot be used because the Hyde fiber and reduce the size of the main structure, construction and maintenance using Hyde fibers are strictly in accordance with the relevant provisions of the state and the practice.
3. Head of fiber stored to prevent sun direct illuminate for a long time.
