Reinforcing fibers are made of a thermoplastic material (polypropylene) and are used to increase the structural strength of concrete in highly demanding applications. With this new production line, Sika is continuing to expand its range of concrete additives and positioning itself as an innovative single-source supplier to the construction industry.

What are the different types of reinforcing fibers?

There are different fibers for different concretes depending on the required performance. The two main types of fibers are micro and macro fibers, defined by their diameter according to European Standards. Micro synthetic fibers are generally used for reducing spalling in high temperatures and crack reduction. Thicker macro synthetic or steel fibers are generally used to increase the mechanical performances of hardened concrete. Sika is a full range supplier of fibers, and other special types and blends of fibers.
