Polypropylene fiber for micro-reinforcement of concrete
BELMIX fiber is a polypropylene fiber of the multifilament type. It is made of isotactic polypropylene, using a high-tech 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.
BELMIX fiber is used for micro-reinforcement of concrete in order to:
BELMIX fiber should be added to dry mixes or directly to the concrete mixer.
It is necessary to mix with a concrete mixer for 1 min for every 1 cubic meter of concrete.
