GFRP composite deformed bar.
Concrete Reinforcing composite bars
Fiberglass reinforcement is a reliable and durable construction material of a new generation, which eliminates the formation of cracks and destruction in the concrete base, and also retains its original mechanical characteristics for a long time.
Features of GFRP rebar
1.High tensile strength: The tensile strength of glass fiber reinforcement is better than that of ordinary steel bars.
2.Light weight: The quality of glass fiber reinforcement is only 1/4 of the same volume of steel.
3.Strong corrosion resistance:Corrosion resistance of chemicals such as acid and alkali can resist the corrosion of chloride ions and low pH solutions, especially the corrosion resistance of carbon compounds and chlorine compounds.
4.Strong material binding force:The thermal expansion coefficient of glass fiber reinforcement is closer to cement than steel.
Application of GFRP rebar
At present, glass fiber reinforced epoxy resin can be widely used in highways, bridges, airports, wharfs, stations, water conservancy projects, underground projects and other fields;
Suitable for corrosive environments such as sewage treatment plants, chemical plants, electrolytic cells, manhole covers, coastal defense projects, etc.;
Applied in many specific engineering projects, including tunnel engineering, foundation pit and slope support, anti-corrosion engineering, anti-electromagnetic interference engineering, brick-concrete structure reinforcement engineering;
