Synthetic Macro fiber
Product Description
Briture Synthetic Macrofiber is made of Polypropylene. Polypropylene macro fiber (PP macrofiber)for concrete is one of pp
fiber used for reinforcing concrete products and mainly used for
structural fibers.
These fibers are wrapped in bundles of water-soluble film and
packed in cartons. When used, just put the whole boxes of the
fibers into concrete.
The cartons and film are dissolved in water and the fibers are
evenly dispersed in the concrete mixture.
Available Length: 48mm, 54mm, 64mm...
Features
1. It can replace the crack prevention and enhancement functions of reinforcement mesh and steel fiber, and the construction is more economical, time-saving and convenient;
2. Restrain the plastic shrinkage and dry shrinkage cracks of
concrete, improve the freeze-thaw resistance, fatigue resistance,
permeability resistance, wear resistance, fragmentation resistance,
impact resistance, bending reinforcement and auxiliary
reinforcement of concrete, and prolong the service life;
3. The surface has been embossed, which greatly improved the
cohesive force between fibers and concrete, and also boosts
shrinkage
resistance and crack resistance.
4. The strength of synthetic macro fiber is not as strong as that
of steel fiber, but the experiment shows that under the same
conditions, each
cubic meter concrete needs 3kg-6kg of synthetic macro fiber, while
steel fiber needs 25kg-40kg. The results show that the concrete
with
macro synthetic fiber has better toughness and anti-microcrack
effect.
Proposed Dosage
The dosage rate is dependent on the actual application however the
minimum dosage range is 3kg/ m3-6kg / m3
Typical Application
Shotcrete, concrete engineering, such as foundations, roads,
Bridges, DAMS, especially in the deformation and toughness of the
higher
requirements of the project, such as mining and water conservancy
and hydropower projects.
