Glassfiber reinforcement

Composite glassfiber reinforcement is one of the most popular and modern building material spread all over the world.

This popularity is explained by the fact that composite reinforcement has some advantages in comparison with steel reinforcement. Everybody knows that steel reinforcement is very heavy and it takes a lot of energy and time to install it. Moreover, it exposed to corrosion which could cause earlier destruction of concrete construction.

Composite reinforcement is light weight and noncorrosive that means that using of it is profitable.

Properties and application of composite reinforcement

Composite reinforcement is the product made of glass fibers bind with thermosetting resins. Its main specialty is lightness mass index calculated using the unit of volume is only 2 g/mm3. Working with this material is much easier and more profitable than working with metal reinforcement. There are less spendings while transporting and armoring.

Composite reinforcement is used while building civil, public and industrial constructions as reinforcing frame of foundations, floors and beams.

In road repairing works composite reinforcement is used for arranging of fillings, traffic-bearing surface in bridge construction and in highway barriers. It is resistant to all types of deicing agents and might be used in all regions.
