MAPEFIBRE ST55

Macro Polyolefin Fibers for High-Ductility Concrete

Mapefibre ST55 are macro synthetic fibers with an embossed surface to help obtain a high level of adhesion in the cement matrix, thereby increasing the ductility of concrete and shotcrete in the post-failure phase. The use of a new generation polyolefin compound provides Mapefibre ST55 with a high level of resistance to attack from carbon dioxide and products containing chlorine. The fibers are also resistant to highly alkaline environments and provide the concrete with long-lasting structural performance.

High resistance to attack from carbon dioxide and products containing chlorine
Particularly suitable for precast elements, shotcrete, extruded elements and other industrial concrete flooring
Compatible with all other MAPEI admixtures used in the manufacture of high-quality concrete
