"Sisiyuan" brand modified polypropylene fiber cross-section of clover type or round, high alkali resistance, good chemical stability, mortar / concrete dispersion excellent bond strength is very strong, per cubic tens of millions of fibers within a three-dimensional chaos meters distributed in the concrete, from a purely physical effect on the reinforced concrete.
Polypropylene fibers used in construction cracking, impermeable material, its use is noteworthy Sisiyuan details below for your use of polypropylene fibers!
Select a different dosage according to the requirements of the project, in the front range of the added amount given, the better the content, the higher the crack, "Sisiyuan" fiber reinforced the role of the physical play in the concrete, the fiber itself is an inert material, Concrete does not react with other ingredients and additives, adding fiber without changing the original mix concrete, aggregates of various performance indicators, no special requirements.
① feeding sequence and methods
When using fiber and sand, stone and other aggregates while adding, adding water to the wet mix
The best in Canada, while the sand and gravel sand and gravel in the middle of the fiber increases, the effect will be better.
② fiber concrete mixer
Stirring time than concrete without fibers slightly longer mixing time 30-60 seconds, to ensure that the fiber can be uniformly mixed in the concrete. (Highly dispersed concrete products in the commodity extend temporarily without stirring time)
In addition, the polypropylene fiber in the use and storage process to prevent prolonged exposure to sunlight, oh.
