Abstract:

For the reinforcement of concrete, fibrillated polypropylene fibres are used. The effectiveness of the reinforcement depends on the fibre geometry as well the mechanical parameters. The production of fibrillated fibres is a multistage process in which formation conditions exert a great influence on the final properties of the fibres. Fibrillated polypropylene fibres were produced by different formation parameters. Mechanical parameters of the fibres: tenacity, elongation at break, and Young modulus were measured. Results of the measurements were analysed by statistical methods. On the basis of the analysis performed, beneficial formation parameters were established.
