When it comes to urban architecture you have to think of polypropylene fiber works in all building materials must not be less that is polypropylene fiber works.

Between polypropylene fiber engineering and construction to do with it? Xiao Bian today to tell you:

Construction Engineering polypropylene fiber use, the first polypropylene fiber works and concrete relationship

"Sisiyuan" fiber used in concrete
1, the proposed amount hspace = 0
Per cubic meter of concrete recommendations added 12-19mm fiber 0.6-1.8kg, the original concrete mix unchanged. (for reference)
2, the use of
Choose a different dosage according to the requirements of the project, in front of the given amount of range, the higher the dosage, the better crack, "slightest touch" from the physical fiber reinforced concrete in the fiber itself is an inert material, concrete does not react with other ingredients and additives, mixing the fibers does not change the original mix concrete, aggregates of various performance indicators no special requirements.
① feeding sequence and method
When using fiber and sand, stone and other aggregates added simultaneously, add water to the wet mix
Preferably plus sand and gravel at the same time to increase the fiber in the middle of sand and gravel, the effect will be better.
② fiber concrete mixing
Stirring time than concrete without fiber slightly longer mixing time 30-60 seconds, to ensure that the fiber can be mixed in the concrete. (Highly dispersed product in the commodity Concrete temporarily extended without stirring time)
3, adjust slump
Due to the thickening of the fibers so that the fibers will be added to increase the viscosity of the concrete mix, making slump slightly. Each project requires a different slump, so before using engineering experiment by adjusting the slump, if the slump does not meet the construction requirements, should not be used to increase the amount of water to increase slump, but should adopt appropriate plasticizing agent or water reducer to increase the slump to meet the construction requirements.
4, the intensity of the test
The addition of fiber does not affect the strength of concrete, but it should be in front of each project according to the provisions have been identified using the concrete mix strength test fiber concrete.
5, knock off the pressure surface
Concrete can be carried out after the mold pressing once completed before the end of the secondary pressure surface until initial setting of concrete, in the face of pressure should make full use of iron or steel trowel, wood tick will not smooth enough fiber.
6, surface type and conservation
Incorporation "Sisiyuan" fiber concrete during molding no special requirements, but should ensure the concrete fully tap.
Incorporation "Sisiyuan" fiber concrete curing, no special requirements, according to the conservation of normal concrete was not due to the incorporation of "Sisiyuan" fibers relax on the early curing of concrete.
7, description
"Sisiyuan" fiber only as a secondary concrete ribs, the main role is to inhibit the production of concrete cracks and improve the impermeability of the concrete matrix to extend the service life of concrete, rather than the main structural reinforcement force.
Therefore, the "slightest touch" fiber can not change the original design of the reinforcement ratio.

Good quality, good price on the election Sisiyuan licensing polypropylene fiber works.
