Chopped pan fiber

Chopped PAN fiber
PAN fiber with high tensile strength, high initial modulus, chemical stability. Therefore this fiber have good anti-corrosion, anti-acid, light resistance, weather resistance, and good dispersion, oil absorption. In practical application, it has strong gripping and bonding with concrete and improve the adhesion of concrete, resistance to fatigue, increased the ability of permeability resistance, frost reistance, impact resistance. Thus, widely used in asphalt concrete and cement concrete engineering project

Applications
High-speed railway, highway, old highway maintenance, bridge, bridge deck maintenance, alteration, runway, various motorcycle parking lot, pavement.

Performance parameter

Use

According to the size of the traffic and load, different fiber content can be the appropriate discretion. The greater the general traffic flow and load, the greater fiber content.
1, Traffic density below 3000, the proposed content of 1.5-2.5 kg / ton;
2, the traffic density of more than 3000, the proposed content 3.5 kg / ton;
3, concrete works, recommended dosage 1 kg / ton.

• The design requirements for incorporation by design parameters.
1.Incorporation process and the original non-incorporation of the mixing process is the same;
2.Fiber will be added when adding dry materials in the mixing time, first dry mixing time to 30 seconds is appropriate; then add wet material mixing, the overall time of less than 60 seconds to ensure a more uniform fiber dispersion.

The number of rolling are proposed to increase, required more than 98% degree of compaction.
