Reinforcement of concrete

One of the retrofitting methods for a variety of buildings is the use of polymeric fibers. This method is economically compatible with traditional building retrofit methods, and it also has the ability to run quickly and easily. Reinforcement with polymeric fibers creates less interference in the use of the building than it does in traditional methods.

FRP materials consist of two basic components: fiber (fiber) and resin (binding agent). Fiber, which is basically elastic, crisp and very resistant. Fiber may be glass, carbon, aramid fiber, in which case the composite products are known as GFRP, CFRP, AFRP, respectively;

Fiberglass reinforced polymer (GFRP)

GFRP has electrical characteristics, electrical insulation and high heat resistance, and has the lowest cost. S-Glass fibers have higher resistance to heat and about one third of tensile strength above E-glass. Special AR-glass fibers are resistant to alkali in concrete, but they are very expensive.

Basalt Insulated Polyester (BFRP)

The basalt fiber has a tensile strength higher than the E-glass fiber and less than S-glass, however, its cost is near the cost of E-glass. This resistance is much better than alcohol and S-glass alkaline in concrete.

Polymer reinforced fiber reinforced (AFRP)

Arid fibers (also known as aromatic polyamide fibers) are high-strength, high elasticity modulus and 40% less density than glass fiber. The cost of fiber is higher than glass fibers and basalt, which makes them less common in structural applications. In addition, aramid fibers absorb moisture.

Carbon Fiber Reinforced Polymer (CFRP)

The carbon fibers have high tensile strength and an elastic modulus. Elastic Module “Carbon Fiber” “Module High” is similar to steel. CFR is popular with the use of high-and-high modulus carbon fiber in the aerospace industry. Normal fiber modules are used by CFRP in the infrastructure industry.
