What is GRC / GFRC?

GRC / GFRC standands for Glassfibre Reinforced Concrete / Glass Fiber Reinforced Concrete, which is a fine concrete reinforced with Alkali Resistant glassfibres (AR Glassfibres).
Read more About GRC /GFRC.

What are AR Glassfibres?

AR Glassfibrea, or Alkali Resistant glassfibrea, are glass fibres suitable for use in concrete which have a high alkali resistance (AR) as they have a minimum zirconium dioxide content of 16%.

Why are Glassfibres used in GRC / GFRC?

Glass fibres have an extremely high tensile strength, compared to their diameter, and this makes them ideal for reinforcing concrete where thin component sections and high tensile strengths can be achieved.

Why are AR Glassfibre necessary for use in GRC / GFRC?

Normal glass fibres would become pitted and deteriorate in the highly alkaline environment of cementitious products such as concrete, which is why only Alkali Resistant glassfibres, with a minimum zirconium dioxide content of 16%, should be used.

What can I do if my question is not answered here?

If you cannot find the answer to your GRCA / GRC / GFRC or other GRC industry questions, then please contact the Association from the GRCA Contact page and we will do our best to answer your questions.
