Barchip Fibres

Barchip Shogun

Barchip “Shogun” is a structural synthetic fibre reinforcement added to concrete and shot crete to replace welded wire reinforcing mesh and steel fibres.

Barchip fibres provide high levels of post-crack performance to concrete, imparting ductility to structures when they have exceeded the moment of rupture. These pictures clearly show how plain concrete crumbles when reaching its peak resistance under loading and whilst cracks appear in the Barchip reinforced pipe, the fibres are able to continue carrying the applied load, making the structure viable, thanks to the multiple fibres that bridge the cracks and hold the pipe together for continued service life.

Benefits

• Flexural toughness equal to steel
• Long term durability ~ corrosion free
• Safer and lighter to handle than steel
• Reduced fire damage ~ anti-spalling
• Reduced wear on concrete pumps and hoses

Barchip “Shogun” fibre can be dosed between 2 to 20 kg/m3 depending on project requirements. Typical dose rates fall in the range of 3 kg/m3 for concrete floors and 5 kg/m3 for shotcrete applications in normal ground conditions.

Barchip “F”

Barchip “F” is a high performance, monofilament, polypropylene fibre used for controlling cracks in cementitious materials. It is used to inhibit the formation of small cracks which can occur through plastic shrinkage, premature drying and early thermal changes, in order to provide utilisation of the intrinsic properties of the hardened cementitious material. They are also used to significantly reduce the risk of explosive spalling during fires.
