What is Barchip made from?

Barchip fibres are manufactured from minimum 550MPa high tensile strength modified polyolefin and similar to steel rebar our structural fibre range has a contoured surface embossing treatment to maximize bond with a cement matrix.

The base polyolefin is highly resistant to the majority of aggressive agents and will never oxidize when exposed to the conditions which cause steel to rust.

Description

It is now widely accepted that the addition of fine monofilament polypropylene fibres to concrete will significantly reduce explosive spalling during fires.

What is Spalling?
Heating of a concrete element causes any retained moisture in the structure to rapidly expand and explode a small layer of concrete from the surface. This will continue during a fire until substantial damage through loss of section occurs in the structure.
Spalling can occur as early as 10 to 15 minutes into a fire when surface temperatures reach as little as 200 degree Celsius.

How do the fibres work?
Once the temperature reaches 160 degrees Celsius, the fibres melt. This creates a multitude of tiny pathways through which the retained moisture can escape in a non-violent manner, thus reversing the increase in pressure within the concrete mass.

The addition of 1 kg/m3 of Barchip F is an extremely cost effective method of fire protection for concrete structures.
