Fiber reinforcing polypropylene (Fiber)

Synthetic fibers made of polypropylene to disperse reinforcement of concrete, mortar and plaster over the entire volume of the mixture.

In receiving the special properties of concrete, plays an important role dispersion reinforcement. As the dispersion of reinforcement can be used polypropylene, basalt, glass, steel, cast iron fiber. These additives can significantly increase the tensile strength, fracture toughness, resistance to shock and other special properties of concrete. These concretes are used for strengthening building structures. The polypropylene fiber is hygroscopic, superfine fiber that will improve the consumer properties of mortars. Alternative to traditional reinforcement - to add in the concrete high-strength fibers - fibers. There are two main classes of fibers: polypropylene and metal. Polypropylene fiber prevents shrink cracking, increases the resistance by static and dynamic loads. The use of polypropylene fibers significantly reduces the time of work. Concrete is brittle enough structural material, its tensile strength is about 10 - 15% of the compressive strength. In order to improve the durability of concrete in tension and bending are reinforced concrete. Reinforcement can be done, including the addition of the concrete high-strength fibers. Thereby changing the very structure of concrete, and concrete acquires new properties.

There are two main classes of fibers for reinforcement of concrete: a polymer (typically polypropylene), metal (steel).

The polypropylene fiber improves the characteristics of concrete in the initial period of recruitment strength concrete.

Steel fiber improves the characteristics of concrete after a set of concrete durability - performs law enforcement functions.

Our company produces fiber length from 2mm to 18mm. The polypropylene fiber has excellent chemical resistance, do not corrode, does not decompose in the environment, cement concrete (as opposed to ordinary glass).

As introduced in the concrete structure: Increases Frost resistance (some manufacturers believe polypropylene fiber alternative vozduhovovlekayuschim supplements) significantly reduces the formation of shrinkage microcracks (which over time tend to develop into a macrocrack), increases the durability of concrete surface, increases the water resistance of concrete - by locking fiber fiber capillaries concrete, due to this reduced corrosion of steel reinforcement in concrete fracture under load, there is separation of the fragments, the fragments remain bound to each other polypropylene fibers, increases the compressive strength and flexural strength, resistance to freeze-thaw cycles, compressive strength and increases the angles ends, thereby eliminating the chips, reduces shrinkage and consequently, cracking in the first hours of hardening concrete, reduces the likelihood of structural damage when removing the formwork.

Despite the fact that the introduction of fiber slump decreases slightly, workability of the mixture, even better, so after the introduction of fiber does not make sense to add water to increase slump.

Instructions:

Fiber is poured into the concrete or mortar before adding the water to the dry mixture. Mixing time 4-6 minutes, to increase the plasticity of concrete or mortar must be added a plasticizer. Fiber is fully compatible with the additives in concrete and mortar.
