Reinforcement of fiberglass construction practice used in steel as a substitute for metallic rolled relatively recently. The main advantage of a fiberglass reinforcement is considered lightweight, corrosive to the oxidation resistance, high tensile strength and reasonable price.
Applying reinforcement, the contractor can be sure that the object will withstand a load calculated and will stand the warranty period.
Produced composite rebar and labeled according to GOST first letters ACK, followed figures rod diameter. For example, the abbreviation stands for 6 ASA armature steklokompozitnaya diameter of 6 mm. More can be found the names of the AKP, the TSA, the ACC where the last two letters indicate the type of material used.
Since the valves of plastic does not respond to acid and alkali in the prepared concrete tolerance of active additives and plasticizers. For example, addition salts, for pouring concrete at subzero temperatures, or other similar reagents.
It is used in the production of reinforcement concrete works, installation of the roadway, repair of foundations, masonry walls, the manufacture of roll-formed structures. In private households valve can be used in landscape design, manufacture pots, greenhouses device, lung canopies. More armature can clean sewage or drainage tubes.
Advantages and disadvantages of fiberglass reinforcement
The composite plastic fittings consists of a bundle of glass fibers bonded with a glued to it spiral rib rigidity. As well as this rib holds the rod in a frozen solution, not letting him move.
The diameter of the rod may be of different size, respectively, with increased or decreased strength. Length is measured fittings meters. Unlike metal GRP is not attached by welding, and for its connection to each other using special clamps.
For more information about the benefits of fiberglass rods can be enumerated list.
- 1. Small glass weight allows the use of the valve in the lung of porous concrete, as well as a bunch of aerated concrete masonry.
- 2. The ability of composite reinforcement not give chemical reaction with It allows you to use it in critical structures. Therefore, there is always a guarantee that it will not rot in concrete products and sustain applied loads.
- 3. In fiberglass very low thermal conductivity - it is unconditional plus. After fires and high temperatures, metal is significantly expanded, thereby deforming concrete products, bringing it to a complete or partial destruction. At the same time, the absence of metal winter inside the product does not cause cold bridges, which increases the thermal protection of concrete.
- 4. Feature fiberglass structure It allows you to transport it in the bays. This, in turn, allows shoppers to save money, measuring out the necessary work for the footage. When buying metal fittings are required to waste that will not come back except for scrap metal.
- 5. fiberglass reinforcement It does not conduct electric currentIt insulator 100%. That is, if in the concrete are present active chemicals, it enters them in the reaction.
More unlike metal carcass reinforcement composite does not shield radio waves, therefore, does not create interference for telephone communication and internet.
In principle, there are no materials, devoid of any flaws, the same thing can be said about the reinforcement of glass fiber.
- Thus, a composite reinforcement can not cook the building structure, and it can not be bent at an angle. In the best case will arc or she generally will break.
- If you hit the glass fibers with a hammer, it will break, and metal bars only get a dent.
- The high heat glass heats up and burns, and only change the color of the metal.
- At fiberglass reinforcement low coefficient of elasticity at break, compared with metal, however it is not advised to use in bearing structures. Personally, I use it to fill the lanes, curbs, light foundation for a bath and a veranda. For slabs and for load-bearing walls to use fiberglass I would not dare.
Although it is a huge disadvantage of composite reinforcement, but the significant advantages it bribed many to use fiberglass reinforcement as a replacement for metal.
But to use it should be considered, at least by making elementary calculations before construction. Otherwise, in the future may be "excruciatingly painful" and sorry for our errors and the desire to save money!
