Product Desciption
6mm PVA fiber chopped strands were cut from polyvinyl formal fiber filament,the chopped strands is designed for asphalt concrete pavement,concrete,mortar,perlite board,etc..It can combine solidly with concrete aggregates, additives,admixtures and cement.This chopped strands anti-acid and alkali,no lose in a strong for 100days,same as well in strong alkali,therefore it will not be any corrosion in alkaline hydrolysis of the concrete.it can maintain the status for 50 years,to play its long-term effectiveness, control of concrete/mortar plastic shrinkage,drying shrinkage,micro-cracks caused by temperature changes and other factors,to prevent and suppress the formation and development of cracks, greatly improving crack resistance of concrete,impact resistance and impermeability,to prevent cracking of the concrete part surface.
SPECIFICATIONS:
PROPERTIES:
1.To prevent concrete cracking:
Concrete cracks occurred mainly before concrete harden,due to the evaporation and transferring of moisture,thereby causing the generating of internal plasticity crack.After incorporation of PVA fiber chopped strands,Inside the concrete to form a homogeneous three-dimensional non-directional distribution support system.delay and prevent early onset and development of plastic cracks of concrete, and therefore play a more effective role in cracking toughening.0.05% volume dosage,the crack resistance can be increased 70%.
2.Improve waterproof and impermeability of concrete.
After the concrete (mortar) incorporation of a small amount of PVA fiber chopped strands,inhibit the emergence and development of early shrinkage cracks and segregation cracks.The concrete (mortar) porosity is greatly reduced, so that the concrete (mortar) impermeability greatly improved,it can be used for concrete projects require high impermeability.0.05% volume adding dosage,impermeability capacity can be increased more than 60%.
3.Improve the impact resistance of concrete.
PVA fiber chopped strands and cement-based material has a very strong binding force,the fiber can be quickly and uniformly mixed with concrete to form a three-dimensional non-directional support system,when the concrete stand tension and shock,evenly distributed and larger numbers of fibers play a role of absorption energy and sharing stress.
4.Improve abrasion resistance of concrete.
Concrete incorporation of a small amount of fiber,it can control plastic shrinkage and plastic settlement cracks,surface texture uniform bleeding pulp film,while the three-dimensional non-directional fiber system can absorb more energy,enhanced concrete abrasion resistance.tests showed that it double the service life after adding fibers,in particular for roads and water conservancy construction project.
5.improve shotcrete anti-fatigue and reduce loss-rebound rate
Concrete mixing a small amount of PVA fibers has a high viscous.For spraying concrete,it can form a thick layer of concrete,significantly reduce concrete rebound rate,therefore,increase the thickness of the molding, reduce material loss in construction,improved project quality and reduce overall costs.
6.Increase the ability of concrete antifreeze and anti-temperature difference.
because fibers having macromolecular structures,when the outside temperature is 40 °C,Concrete incorporation of the fibers has a shrinkage; -40°C, the glassy and crystalline macromolecules has resistance to shrinkage,these properties make up concrete's thermal expansion and contraction properties,ease stress in concrete caused by temperature changes,to prevent extended temperature cracks.It can be widely used in cold areas concrete projects.
7.Good finishing properties.
PVA fiber chopped strands is a fine monofilament fiber,unlike some other rigid additive materials,which will expose concrete surface and affect appearance.Instead,its detailed structure is properly trimmed,it can make the concrete surface softer pleasing visual effect.
8.Help to improve production efficiency and economic benefits.
In order to make a reasonable economic evaluation,comprehensive economic efficiency indicators need consideration of factors,like long-term benefits ,short-term benefits,one-time investment,maintenance and materials management costs,easy and difficulty of construction,etc. Practical applications of the fibers could prove using fibers can achieve better economic efficiency.
APPLICATION FIEDS:
1. concrete septic tank,basement,roof,reservoirs,external plastering, etc.used as crack impervious material,the effect is particularly evident.
2. Shotcrete for top and wall of tunnels,mines,underground,civil air defense projects . Concrete's rebound and shedding no more than 4%-5%.
3.dams, cisterns,drains,swimming pool.Reduce cracking,reduce permeability and enhanced corrosion resistance.
4.situations require high index of fatigue resistance,impact resistance,durability.like docks,roads,bridges,streets concrete pavement,airport,etc.
5.precast concrete sheets,tubes and so on.Increase the crush resistance, reduced shrinkage and settlement cracks.
In general, PVA fiber chopped strands for all types of concrete construction.Reduce concrete cracking,reinforced concrete impermeability and toughness,thereby improving the life of the building.
RECOMMENDATIONS:
It is a physical effect the reinforcement for concrete / mortar enhancement,rather than chemical action.There will be no conflict and chemical reactions with concrete aggregates,admixtures,cement,and it has good adaptability with concrete materials,it does not affect the addition of other concrete admixtures usage,their function independently of each other.
PVA fiber can not replace structural reinforcing material,don't decrease the body structure size because of using PVA fiber.PVA fiber alone could not solve the settlement,massive concrete hydration heat and a strong external shocks occasions;It also need maintenance and following of construction regulation.
RECOMMENDED DOSAGE:
Generally to meet the requirements for surface crack,1 CBM concrete mixing 1kg fiber. For special using like basement seepage prevention need 1.5kg/m3 to 3.0kg/m3,abide by engineering design criteria.
STORAGE:
The PVA fiber chopped strands should be keep dry in their original cartons and stored in a suitable place,preferably at room temperature with 35-65% relative humidity.Avoid the sun, rain and fire
PACKAGING:
SHIPMENT AND TRANSPORTATION:
Shipment by sea bulk loading,one container 8000kg.
