Advantages fiber

1. Reduces microplastic shrinkage and cracking during the curing of concrete:

Improves the ability of concrete to the strain without fracture at a critical period - 2 ... 6 hours after laying, thus reducing the size and number of cracks that perpetuate the greater internal strength of concrete;
At a later stage when the concrete is dry and begins to shrink, fiber connects the edges of cracks and reduces the risk of breaking;
Reduces water allocation through the effective control of hydration, thus reducing the internal load. By monitoring the performance of water on the surface decreases the formation of cracks in plastic settling.

2. Resistance of concrete to freeze / thaw:

Fiber makes the concrete a small number of air, allowing free water to grow and shrink in the cycle of freezing / thawing,
Fiber reduces the number of water channels in the concrete, resulting in lower permeability gives greater resistance to freezing;
Fiber controls the movement of water in the concrete, providing a more efficient hydration of cement, and increases the compressive strength on the first day. Prevents rising to the surface of cement and sand

3. March. The resistance of the concrete impact:

Concrete containing the fiber, has a far greater impact resistance and resistance to splitting in comparison with conventional concrete, tests show 5-fold the excess under this factor. Fiber provides more protection from destruction edges compounds in concrete floor slabs and precast reinforced concrete structures;

4. Resistance of concrete to abrasion:

Abrasion resistance of concrete with Fiber at 6 hours increased by about 10% and the whole can be greater than 30%. The ability of fiber to control the movement of water in the concrete mix reduces the possibility of segregation of fine particles of cement and sand, which provides a more efficient hydration of cement and in combination with the best grip cement gives a more solid and durable surface.

5. Fire resistance of concrete:

Fiber increases the fire resistance characteristics of concrete. Concrete with Fiber is more resistant to bending after exposure to a temperature of 600 ° C for 1 hour. It also increases the resistance of concrete to splitting after exposure to combustion of hydrocarbons (2 hours at 1100 ° C).

6. Increased resistance to penetration of water and chemicals:

Fiber reduces the permeability and water absorption of concrete. This is achieved by reducing the number of holes in the concrete from speaking of water, so water, chemicals and dirt are absorbed more slowly. Fiber is resistant to alkalis and most chemicals used in manufacturing processes. Concrete with polypropylene fibers are widely used in water networks, such as reservoirs, septic tanks for sewage, waste-gates, ports, docks, sea barriers, as well as concrete roads and bridges, particularly important where high resistance to penetration antiobledenyayuschih salts.

7. Fiber - cost alternative to steel mesh:

Fiber can be regarded as cost-effective alternative to controlling the formation of cracks steel grid. Fiber does not affect the strength of concrete in bending. Steel mesh is stretched and has some value only after the concrete cracked. As an alternative, fiber help prevent cracks forming in the concrete in a plastic state.
