Features and benefits of composite reinforcement - Review application

Many times I had to do construction work, which involves the use of rebar and other reinforcing elements.Unfortunately, until recently, I did not know that the metal reinforcement can opt for a more refined version, which is based on composite materials.I would like to present you my review about this product, based on a personal experience of use.

So, composite rebar is usually made on the basis of fiberglass.Its structure is a plurality of fibers, which provides a link between the chemical composition is rather complicated.I had to deal with several types of composite reinforcement, but the best option in terms of quality and price ratio, I would call a plastic reinforcement.The structure of this construction element is as follows:

• main reinforcing barrel.It is this component determines the strength characteristics.It consists of, arranged in parallel fibers are fastened together with polyester resin material;
• outer shell.With the help of rebar most firmly fixed with concrete.Typically, fiber reinforced shell simply screwed onto the basic core.To ensure a more firm grip shell can be sprayed onto the sand base.

Generally speaking, the physical body is fiberglass reinforcement can have a variety of different configurations.It depends on the variety of the extent justified by the new version with technological and financial point of view.For example, I had to work with fittings, which bore a "pigtail" of carbon and basalt filaments and the outer layer resembles beaming bazaltovolokon double oriented.

Pros composite reinforcement

During the operation I was able to identify the following advantages of composite reinforcement:

• Plastic does not rust and does not lose its pristine properties even at permanent contact with aggressive media.It turns out that composite rebar can be clearly attributed to the material constituting the first category of chemical resistance;
• strength tensile load, which has a composite rebar is almost 3 times higher than the figure for the standard goods of metal;
• weight composite reinforcement is minimal, it is 5 times less than that of the steel rod of the same diameter.This leads to the advantage that significantly reduces transportation costs as reinforcement to the site, and the total weight of the concrete structure;
• Thermal expansion of composite reinforcement is almost on par with the coefficient of thermal expansion characteristic of the concrete;
• use of composite reinforcement may be in the temperature range from minus 70 to 100 degrees Celsius.It turns out that it is absolutely safe.
