Nano-Composite Rebars

Glass Fibre Reinforced Bars (GFRB) are advanced material for the replacement to classic steel and ideal substitute with a wide application in reinforcement technology as well as other related building sectors. For composite rebars, there is no need to apply any anticorrosive coating on steel reinforced bars, which is a very expensive process resulting in investment losses. GFRB is an alternative to traditional steel bars for concrete reinforcement. It is a new innovative and more economical technology, as it does not require expensive maintenance and repairs after a long time of use as in the case of reinforced concrete structures

Unique features of CFRB:

​

• Decrease of the weight of a structure by use of a smaller diameter of GFRB, which are characterised by 2-3 times greater tensile strength than steel rebars.

• Decrease of thickness of concrete, which reduces costs of embedding, transport and stocking of bars at a construction site

• Reasonable savings as compared to steel reinforcement, owing to larger distances between bars

• Decrease in costs owing to easy machining and possible use in cut and drilled elements

• Resistance of difficult atmospheric conditions and increased durability owing to high chemical and corrosive resistance
