Polypropylene fiber to reduce the appearance of microcracks and micro-reinforcement of cement-sand solutions
Polypropylene fiber is a multifilament type fiber. It is made of isotactic polypropylene, using a high technological process. Polypropylene fiber is the only smallest (69 microns) polypropylene fiber that combines mechanical and chemical properties. Polypropylene fiber is hundreds of millions of the finest silky polypropylene fibers in each 1 m3 of concrete, evenly distributed throughout the mass and accepting shrinkage stresses of concrete, which significantly reduces the appearance of microcracks.
Fiber is used for micro-reinforcement of concrete in order to:
Polypropylene 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.
Polypropylene fiber is dosed in the proportion:
0.6 kg – 2.7 kg for each 1m3 of concrete;
0.15 kg-0.3 kg for each 1m3 of foam concrete;
0.6 kg for cement-sand mortar, screed.
Polypropylene fiber is supplied in cellulose bags of 0.6 kg.
