GRC

Modern technologies allow to produce new building materials with high performance.One of such modern construction materials is GRC or SWFs, which is a kind of fiber-reinforced concrete.

Composition

The structure of GRC includes the following components:

• cement;
• filler (sand);
• fiber glass;
• water.

That is, the composition of the material is similar to a conventional reinforced concrete.However, through the use of glass fibers as a reinforcing material, GRC has better performance characteristics.This made it possible to significantly expand the scope of use of the material.

Application

The main application - the creation of unusual architectural forms, facade decorations, namely:

• cladding panels of GRC;
• balcony railing (loggias);
• architectural and decorative details;
• roofing imitating roof tiles
• also used in the construction of bridges, overpasses.

Specifications GRC

1. Compressive strength - 49-84 MPa;
2. Side-altar of tensile strength in flexure - 21,0-32,2 MPa;
3. Thermal conductivity - 0,52-0,75 W / cm2 *? C;
4. Frost - F150-300;
5. Fire - high (above concrete indicators);
6. flammability - does not burn;
7. Waterproof - W6-20.

These specifications allow the use of GRC in various climatic conditions without risking the loss of its performance properties.In addition to its primary purpose material also will be a good insulator and shumoizolyatorom.

Benefits

to know the benefits of GRC, it is necessary to compare it with similar construction materials.Its main "competitor" - a reinforced concrete structure.

So, reinforced concrete structure consists of cement, sand and metal fittings.To protect the valve from moisture and corrosion, technological dimensions of reinforced concrete block increases.In addition to the heavy metal fixture has added forced extra weight of the unit.That is, according to its weight concrete block will be harder to GRC.Therefore, stacking these blocks requires greater involvement of specialized equipment and labor.

The GRC as a reinforcing material acts or alkali-resistant ordinary glass.In block glass fibers have a small cross section and great length.This makes it possible, with a small weight GRC unit, significantly increase its durability.

Compared with conventional concrete, is the strength characteristics of GRC will be about, so - the impact strength is 10-15 times higher tensile strength / flexural 4-5 times.All the indicators say about the advantages of this material over conventional concrete and reinforced concrete structures.

In addition, GRC is very easy to take a variety of architectural form.With it you can easily create both simple and complex multi-level composite scenery.

Here you can see photos and video of this modern building material.

Disadvantages As with any building material from the GRC has its drawbacks.He quickly hardens concrete, so it should be laid quickly.Also, ready-made products from this material are more expensive than its counterparts.

Durability of GRC operation depends on its structure and purpose.For example, if the material is used for construction of the foundation, as a reinforcing material is necessary to use alkali-resistant glass fibers.

Feedback from people using GRC in various types of construction, this material has enormous potential applications and a significant advantage over similar building materials.
