To date, concrete reinforcement has coordinally changed due to the use of non -metallic elements, such as reinforced mesh, reinforcement and pipes made of plastic, also various fibers and polymer fibers.
One of the types of reinforcement is polypropylene fiber -fiber, which reinforces concrete over its entire thickness and reinforced concrete products, unlike the metal structure of the reinforcement, which lies and reinforces only one plane. It is worth noting that some hotels of Nizhny Novgorod are built using polypropylene fiber -fiber.
The use of polypropylene fiber for reinforcement of concrete, the builders immediately forgot about the following problems of this material:
Excessive dust formation and shrinkage deformation disappeared,
The resistance to various influences has increased significantly, such as mechanical and chemical.
With the addition of polypropylene fibrum to gypsum or cement solutions, their qualitative indicators are largely increased. At the cost of fiber -fiber is much cheaper than steel reinforcement. Also, polypropylene fiber protects against microcracks, as well as reducing concrete voltage during filling and subsequent drying, setting and shrinkage. Using a steel reinforced net, it is impossible to achieve a similar effect. Because steel reinforcement allows you to maintain the integrity of the structure only after the cracks have already appeared.
