CHRYSO®Fibre Syntec 12

CHRYSO®Fibre Syntec 12 Synthetic microfiber, is a new generation polypropylene micro fibre for reinforcement of concrete.

CHRYSO’s Unique technology combines ultra thin diameter with ultra high strength, resulting in the highest level in plastic shrinkage crack prevention available.

Hundreds of millions of high tensile, high modulus filaments per dose of CHRYSO®Fibre Syntec 12 create an extremely dense, three dimensional network in any cementitious application.

  • CHRYSO®Fibre Syntec 12 has a good adherence to the cement paste, which increases strain capacity.
  • CHRYSO®Fibre Syntec 12 acts as fire protection for the concrete against spalling. CHRYSO®Fibre Syntec 12 melts under high temperatures allowing passages to be formed within the concrete that allows the steam to escape.
  • CHRYSO®Fibre Syntec 12 will increase the fire rating of concrete due to its 32 μ diameter.
  • CHRYSO®Fibre Syntec 12 slows down bleeding, reduces permeability and avoids spalling when removing the form.
  • CHRYSO®Fibre Syntec 12 decreases the risk of cracking during the pre-hardening stage. This means the damaging effects of plastics hrinkage are eliminated.
  • CHRYSO®Fibre Syntec 12 improves abrasive resistance, resistance to impacts (surface, joints, angles), resistance to frost/defrost cycle, fire resistance and resistance to chemical attack.
  • CHRYSO®Fibre Syntec 12 is not a replacement to structural reinforcement, but it is a very good alternative to mesh reinforcement that is used to control plastic shrinkage and plastic settlement cracking. This reduces cost and construction time while making the construction process easier.
Domains of application

CHRYSO®Fibre Syntec 12 is recommended for all concrete and mortar mixes where reduction of cracking caused by plastic shrinkage, plastic settlement, thermal expansion and contraction in concrete is desirable. It also contribute to reduce water migration and to increase the surface resistance to impacts, abrasion and shattering.
