Polypropylene fiber for micro-reinforcement of concrete
BELMIX is a polypropylene fiber of the multifilament type. It is made of isotactic polypropylene, using a high technological process. BELMIX fiber is the only smallest (69 microns) polypropylene fiber that combines mechanical and chemical properties. BELMIX consists of hundreds of millions of the finest silky polypropylene fibers in each 1 m3 of concrete, evenly distributed throughout the mass and accepting the shrinkage stresses of concrete, which significantly reduces the appearance of microcracks.
