B-STRATOS 20 are polypropylene fibres, length of 20 mm. and 10 m m, with an easy dispersion and use recommended in concretes for industrial and civil floors, 15 to 30 cm. of thickness, used to eliminate cracking due to shrinkage in plastic state. Fibres are treated to improve wetting and dispersion in the paste of cement and on the other side to increase capacity of contact and adhesion between fibres and concrete in hardened solid state.

Weight reduced and easy application. Higher chemical resistance than steel (acids, alkalis, salts, etc.) Resistant to alkalis in cement. No oxidation or rotting. Damp-proof properties. High traction resistance Excellent adherence to the concrete matrix. Low coefficient of elasticity Control of plastic shrinkage with cracking reduction. 0,6 kg of product replace 25 kg. of metallics cramps. Reduction of retraction joints.
