What are concrete fibres used for?

Concrete fibres, i.e. concrete companion fibres, are commonly used as a raw material for polypropylene resin and are specifically designed to prevent or reduce the initial plastic cracking in cement concrete, acting as a "secondary reinforcement" for cement concrete.

Concrete fibres are made by blending, spinning and stretching modified masterbatch into polypropylene chips. The concrete fibres are treated with special anti-static and anti-ultraviolet rays, so that the fibres are evenly dispersed in the concrete and can play their role for a long time; the "Y" cross-section of the fibres increases the surface area of the fibres; the "New Silvic" brand fibres are chemically and physically modified, and the surface is Rough and porous, which greatly improves the bond between the fibre and the cementitious aggregate. Concrete fibres improve the performance of concrete by reducing the occurrence and number of primary cracks in the concrete, without any conflict or chemical reaction with concrete aggregates, admixtures, mixers and cement, and are therefore well adapted to concrete materials.
