Abstract
The present invention relates to a polymer composition for forming fibers for reinforcement of cement-based composites, polymer fibers made from the composition and methods of making the polymer fibers. The polymer composition comprises an olefin polymer and a bonding agent comprising vinyl alcohol based polymer, a pozzolanic material or a combination thereof.
Claims21
A method of forming a polymer fiber, the method comprising:
- a) admixing a bonding agent with an olefin polymer, wherein the bonding agent comprises a vinyl alcohol based polymer and a pozzolanic material;
- and
- b) extruding said admixture at an extrusion temperature sufficient to melt at least said olefin polymer to produce the fiber,
- wherein said olefin polymer is about 50% to about 99% and said bonding agent is about 1% to about 50% by weight of said admixture.
