Polypropylene fibers of polypropylene and a variety of organic and inorganic materials, the extraordinarily complex technology refined products in concrete to constitute a three-dimensional chaotic distribution network supporting role, so that micro-cracks in the hardened pre-formed concrete in obstruct the process of being opened, it is difficult to further open. You can then trek cracking resistance of concrete, concrete cracking impermeable to improve function, is the mortar, concrete engineering crack, seepage, wear new insulation material aspirations.
■ crack: trek concrete plasticity of time before non-structural cracks cracking tune.
■ impermeability: trek impermeability only tune, is a useful self-rigid waterproof material.
■ Volume Scheme: 0.6-1.8 kg / m3, impermeable concrete cracking is usually 0.9kg / m3.
Polypropylene staple fiber characteristics:
1. high strength and elastic modulus, is conducive to the mechanical function of the concrete.
2. The strong bond with the cement surface hydrophilic conducive to hanging ash disposal, trek strength.
3. Excellent dispersion, not hold together, to ensure that its useful function of promoting cracking.
4. chemical fiber function stable, highly acid.
Concrete reinforcing functions:
Prevent mortar, concrete cracks shortening; improve my patience degeneration concrete; reinforced impermeable crack function; trek impact strength of the wall; trek peel resistance of abrasion; trek impermeability, freezing and thawing; enhanced protection muscle function; prevent mortar dry and prevent cracks widened.
Polypropylene staple fiber uses:
For cracking putty powder, insulation mortar, concrete, construction level, the walls, floors, pools, basements, and access bridge project, with a crack impermeability, wear resistance trek, trek impact, explosion, also resistant to pull away, the old and new interface bonding trek.
