For construction companies, the sale of fiberglass reinforcement, which is made of polymers and hardened with continuous fiber. It is used in concrete structures instead of classic steel rods for unstressed and prestressed reinforcement. But the use of fiberglass reinforcement in concrete capacitive structures and to strengthen the coastline is significantly limited due. Advantages and disadvantages of fiberglass reinforcement with the main drawback of the reinforcement made of fiberglass is the inability to use in ceilings and supporting structures, which must comply with the requirements of fire resistance. Although the use of polymer rods for reinforcement is limited by places where the temperature heating factor is excluded, this variety of reinforcement is different in many advantages: the reinforcement is not exposed to electromagnetic fields, alkalis, salts and acids; With a small extension coefficient, fiberglass reinforcement is characterized by a high elastic module and resistance to stress loads; Due to the influence of low temperatures on polymer rods, their strength characteristics are not lost; The formation of cracks in concrete and reinforcement impulses are excluded. The use of fiberglass reinforcement reinforcement from fiberglass is used in various areas of construction, including reinforcing the roadway, lighting supports, insulating traverses, fences of bridges and flooring, foundations of various designs. Such material is increasingly used in reinforcing fence, paving and road plates, railway sleepers and heat -saving three -layer structures. Fiberglass reinforcement will be required during restoration work, because due to insignificant weight it does not weight the total mass of the repair, as well as during reinforcement of wooden glued beams. Although fiberglass reinforcement cannot be welded, like metal rods, it can be connected thanks to cable polymer screeds.
