Areas of application: polypropylene plastic fiber type (toughening polypropylene synthetic crude fibre) is mainly used for concrete panel structure, strengthen and local reinforced concrete structure and injection engineering, dedicated to highway, railway, tunnel, culvert enhancement, carbon fiber reinforced concrete is using polymer fiber materials, through special craft processing, processing of monofilament fiber.Its biggest feature is high strength, low anti-embrittlement, stretch, free from contamination.Alternative steel fiber is used to increase the crack resistance of cement concrete.. It keeps the original traditional fiber concrete caking property, high temperature stability, fatigue durability, low temperature crack resistance, more greatly improved fiber in the concrete workability and dispersion, can be more evenly bearing the concrete structure of the main load;With high strength, corrosion resistance, high temperature resistance, chemical stability strong, and concrete around strong grip strength, anti-aging, resistance to wind erosion, and resistance to acid and alkali, diamagnetic rust...More stereo to play the role of reinforcement and bridging.And easy construction, no damage to equipment.Highway pavement, bridge deck pavement, the apron, dock yard paving, concrete face rockfill dam panel, industrial building ground floor, warehouse, etc., used to improve crack resistance of these panel structure, flexural strength, flexural toughness and impact resistance, fatigue resistance, etc.
Directions for use: polypropylene plastic fiber type (toughening polypropylene synthetic crude fibre) effect on the enhancement of concrete is a kind of physics do not change the design of concrete proportion.Length: the length of the carbon reinforced fiber to general engineering 25 to 60 mm advisable.Unilaterally in concrete proportioning design: normally, and dosage of carbon reinforcement should be 5 to 6 kg, dosage of bridge deck waterproof layer such as double.Don't have to change the amount of other material.Mixing method: because the carbon reinforcement has good dispersibility, don't need to attach other mixing conditions, using traditional mixing process.Or choose biaxial horizontal forced mixer.Note: after adding fiber, concrete mixture viscosity increases, road roller should be 2-3 times more than ordinary mixture compaction.Or 30 seconds, as appropriate to extend the time of vibrated to concrete surface passivation for plaster again after a little, in order to avoid out of the fiber.Maintenance should be in accordance with the requirements of the normal concrete.
Note: 1, do not reduce the reinforcement ratio of reinforced concrete structures.2, not reduce the construction quality management requirements, still should be in accordance with the relevant national technical regulations, carry out the construction and maintenance.
