Polypropylene fibers are used to improve the quality of concrete, mortar and screed, and to reduce cracks and damage caused by tightening of concrete. They are packed in paper bags from 600 to 900 gr which are used for 1 m3 concrete ( 1 bag = 1 m3 concrete)
Properties:
environmentally friendly product
absolutely inert and stable fiber, no corrosion
chemically neutral for all cements and accessories
has a high resistance to alkalines
not magnetic
antistatic
indefinite product lifetime
to improve all the important properties of concrete, mortar and screed
significantly reduce the formation of cracks due to shrinkage of cement binder
they increase compressive strenght, flexural-tensile strenght and firmness to splitting
they increase the water holding capacity of fresh concrete and screed
they increase water impermeability
they increase resistance to freezing and thawing cycles
they increase the wear resistance of the upper surface and the impact resistance
they increase the fire resistance
they reduce damage, and therefore the cost of repairing
fibers are arranged three-dimensionally and uniformly throughout the mixture
are not harmful to humans, nor in the application process, nor later for residents of buildings
Application:
all types of concrete
screed and mortar
basement walls
curbs
swimming pools
pool bottoms
garage entrances
Preparation and dosing:
Polypropylene fibers are added to the dry mix or immediately after dosing water
Ideal mixing time is 1 minute/m3 concrete
Results in a homogeneous, easily workable mix
Mixtures with fiber can be pumped or "sprayed"
For easier processing it is recommended to apply from
Polypropylene fibers are from 12 to 18 mm long, packed in the bags of 600 to 900 g.
