GRC Beton


What should you choose, GMC or TRC?

The fundamental difference between GMC and TRC is the use of zirconium glass fibre in them.
GMC (glass fibre modified concrete, GFRC in American terminology) are concretes and cement mortars modified with glass fibre. These products are thus based on cement and glass fibre is used to improve the mechanical and rheological properties of the modified materials (fibre reinforcement). The finished products will be construction chemicals: plasters, grouts, repair mortars, glues and self-levelling floorings.
TRC (textile reinforced concrete), on the other hand, is concrete reinforced with glass textiles and mats in order to increase its tensile strength and other mechanical parameters. These concretes are often described by professional literature as “intelligent concrete structures”. Materials reinforced with zirconium glass fibre can transfer greater forces without breaking. As a result, TRC replaces lightweight steel reinforcement in materials it cannot be used in, e.g. in thin concrete layers, due to the thin concrete cover, which can cause accelerated corrosion of the steel in the concrete and the loss of its reinforcement properties.
Prefabricated components made of the above mentioned materials are characterised, among others, by: low weight and high load carrying capacity at minimal cross-sections, which allows for creating large-scale architectural elements with complicated shapes. Another advantage of theirs is their extensive shaping potential: by bending or reproducing. Furthermore, glass fibre is a mineral additive and can be fully recycled, thus materials containing it can be regarded as “green products”.
