Composite materials steadily replace their predecessors in all construction fields. More and more often traditional construction materials cannot meet the contemporary requirements because they have already exhausted their potential. New composite materials are taking over. They are produced of a combination of two and more synthetic materials. Contemporary composite materials are highly endurable, light, low-wearing, they can be used in severe environment, they are accessible, and this is by far only an incomplete list of specifications that create a great potential of contemporary composite materials in terms of their range of applications.
Construction sites in many regions of our country and abroad have proven that the use of composite mesh in construction industry accounts for 1.5 – 2 times less cross fractures and rutting, because this mesh is resistant to corrosion, humidity, temperature fluctuations and has a considerable tensile strength. Composite construction mesh is produced of fiberglass reinforced plastic fibres positioned in two mutually perpendicular directions and fixed in the contact assembly. Composite construction mesh is delivered in coils, which saves time.
Composite mesh is used to reinforce: concrete slabs, beams that are laid in the environment with high humidity and exposed to corrosive environment. E.g.: flooring materials, bathrooms, chemical production sites, agricultural buildings, inshore buildings and constructions, brick and stone walls of buildings and constructions; concrete elements exposed to chemicals and salts. E.g.: flooring materials for production sites, inshore buildings and constructions, cooling towers, bridges, dams, etc.; concrete road surfaces treated with deicing fluids and salts.
Advantages of the composite mesh for masonry.
Having the same diameter as the metal mesh, the composite mesh is 3-4 times more durable, i.e. it is able to hold higher tension like extension, bending and tearing from the wall.
Excellent resistance to chemical agents, salts and corrosion even in humid and corrosive environments.
The most widely used metal mesh (50х50х3 mm, 0.5х2 m) weighs 2.22 kg/m2. A similar mesh made of fibre-reinforced plastic rebar weighs 300-360 g/m2, i.e. it is 6 times lighter.
0.46 W/m2, while for metal products this index reaches 40-60 W/m2, i.e. it is approximately 100 times higher. This means that metal mesh in the wall serves a thermal bypass and reduces energy performance of construction. The use of composite mesh eliminates this problem.
Low elasticity modulus allows to rapidly and effectively damper vibration.
