Premix fibrecrete is a polypropylene fibre-reinforced concrete which offers benefits in both the fresh and hardened state.
When fresh, both bleed and plastic cracking are considerably reduced. The effect on early age tensile strength during hardening is also beneficial, and after hardening the fibres improve the toughness and general durability.
One of its main applications is in pavement and floor slabs where crack control and durability are of particular importance. Premix fibrecrete provides an economic alternative to crack control steel, subject to proper design considerations. The use of fibres compared to A142 mesh in a 150mm slab will result in cost savings. Fire resistance is also enhanced.
Note: Polypropylene fibres are not a substitute for structural steel reinforcement. Steel fibres are also available - please contact our technical department.
