SHAPED FIBRE CEMENT PRODUCTS AND REINFORCING FIBRES FOR SAME

摘要

The invention concerns polypropylene fibres for reinforcing fibre cement products and the method for treating said fibres and the fibre cement products reinforced with such fibres. The fibres comprise, at the surface, an organic polymer deposit containing olefinic monomers and containing polar groups; said deposit is obtained by surface treatment using an aqueous dispersion of said polymers. Said fibre cement products have enhanced properties of breaking strength under stress and better resistance to cracking.
