Fibre Types
Different fibre types are used to deliver different performance requirements. Short, thin synthetic fibres are used for fire protection and crack reduction, whilst long synthetic or steel fibres generally come into play to increase energy absorption. One size doesn’t always fit all, and special requirements demand special fibre materials and shapes – Ultra High Performance Concrete (UHPC) requires short fibres with a high E-modulus, for example. Sika provides solutions for all these eventualities, as well as other special types and blends of fibres.
