fibrous concrete

Today we consider the fiber concrete building material with unique technical characteristics, which led to its growing popularity in the construction of monolithic structures.So what exactly is fiber concrete?

Composition

fiber-reinforced concrete is a mixture of fine-grained concrete with a fiber (a reinforcing filler).The fiber mixture is evenly distributed and mixed.Today, the most popular is considered fibrous concrete with fillers from:

• steel;
• glass;
• basalt;
• polypropylene.

With the introduction of any fiber in the concrete matrix composite material is formed with the other, differing in the required direction specifications.Introduced in the concrete reinforcement fibers create the effect.

Specifications fiber-reinforced concrete

Fibrous concrete has excellent performance characteristics: a combination of ductility with excellent flexural strength and elongation, excellent toughness, crack resistance.Technical characteristics of fiber-reinforced concrete depend on the filler.For example, fibrous concrete, reinforced with fiberglass fully called GRC has:

• density from 1700 to 2250 kg / m3;
• compressive strength of from 490 to 840 kg / cm2;
• tensile strength in bending from 210 to 320 kg / cm2;
• modulus (1-2.5) h104 MPa;
• thermal conductivity of 0.52 to 0.75 W / cm 2 x ° C.

Compared with the traditional concrete, this material is much more durable, more wear-resistant, resistant to aggressive manifestations of the environment.And he:

• shockproof;
• waterproof;
• hardy;
• resistant to extreme temperatures;
• fireproof;
• does not tend to shrink.

By improving the basic parameters of the structure can be reduced thickness, thereby reducing much of its mass.Therefore, fiber-concrete blocks are used where required a significant reduction in weight of the structure.In addition, the fiber concrete is completely safe for human health.

Primenenenie fiber-reinforced concrete

Environmental security fiber-reinforced material can be used in the construction of residential houses.By the application of the material relates manufacture:

• bulk and industrial floors;
• road surfaces, bridges, landing strips aerodrome;
• production of curbs and facade panels;
• cellars;
• garages, etc.

enjoys great demand material where necessary improved crack resistance and impact resistance of coatings.Therefore, today it is an indispensable material for the floor.One of the important directions of fiber concrete - architectural decoration for the restoration of monuments.Wall cladding panels in the reconstruction of old buildings and construction of new possible to obtain a beautiful and durable facade.

Benefits

reinforcement fiber of conventional concrete is much less expensive than the reinforcement grids and frames.It does not simply reduced material costs, but it takes time to manufacture.With the addition of fiber decreases the consumption of concrete.Even after the expiry of the term of operation, the concrete will crumble and fall apart pieces as usual, because fiber concrete gives a certain viscosity.

Fiber works seamlessly and with mixtures with other compounds.Widespread use of the fibrous fiber for making gas and foam concrete mixes.When aerated introduced fiber observed resistance porization process.Also, increased strength and foam blocks, if the fiber is added into the foam.

Disadvantages

deficiency in fiber-reinforced concrete is only one - is its higher cost compared to conventional concrete.However, when you consider its durability and resistance to wear, the price difference will be compensated.Looking
