What is glass fiber concrete for the facade, production technology, characteristics, composition

Glass fiber concrete is a contemporary material that is becoming more and more popular for use as facades. It is the perfect option for a variety of construction projects because it combines the strength and longevity of conventional concrete with the extra advantages of glass fibers.

Alkali-resistant glass fibers are mixed with cement, sand, water, and production technology to create glass fiber concrete. This combination produces a material that is extremely strong and lightweight, able to withstand severe weather while also lowering the structure’s overall weight.

The high tensile strength of glass fiber concrete is one of its primary qualities, as it improves the material’s resistance to cracking and deformation. Its versatility also makes it a flexible option for architects and builders, enabling the creation of complex designs and shapes.

Glass fibers, water, fine aggregates, and Portland cement are usually the ingredients of glass fiber concrete. Together, these elements produce a material that is not only robust and long-lasting but also green in that it frequently uses less raw material than conventional concrete.

What is it

Because modern technologies are evolving so quickly, building materials are becoming increasingly high-quality. Novel solutions with uncommon qualities and benefits keep coming up for sale. Among them is glass fiber concrete, which is made of concrete reinforced with fiberglass, increasing its degree of elasticity and helping to develop additional performance attributes.

Composition and main features

Glass fiber serves as a filler and cement mortar makes up the composition of glass fiber concrete. These raw materials give the material more strength and resistance to compression and stretching. Unlike traditional types of concrete, fibrous additives are distributed haphazardly and have a small cross-section but increased length.

To increase the strength of reinforced concrete at the production stage, it is reinforced with metal rods. Their task is to absorb tensile loads and prevent deformation of the structure during operation.

Nonetheless, reinforcement adds to the block’s weight and dimensions. Glass fiber concrete does not have this kind of feature. Despite having a lower mass, the material can handle heavy loads and distributes their absorption.

Fiberglass exhibits no fear from tensile and compressive forces, corrosion, or the adverse effects of sudden temperature changes. In addition, compared to steel rods, it has a larger total cross-section. The block becomes lightweight, small, and reasonably priced as a result. In addition to mixing the mixture, polishing or painting is done to decorate the surface of the product.

The material’s range of applications is fairly broad.

1. Facing panels.
2. Enclosing structures for loggias, balconies and stairs.
3. Elements of landscape or interior design.
4. Elements for roof decoration.
5. Decorative types of plaster mix.

Additionally, the material is utilized in the building of overpasses and bridges.

The following elements are chosen as the composition when glass fiber concrete production begins:

1. High-grade cement mixtures – act as a binder. When choosing cement, it is better to give preference to aluminous compositions, since they are characterized by good crystallization and the ability to maintain strength without losing water resistance.
2. Quartz sand – is used as a filler.
3. Fiberglass – takes up 3-5% in the composition.
4. Liquid — designed to obtain the optimal consistency.
5. Additional components — determine the operational properties of concrete. Dyes can be added to the composition, giving the surface a tint.

Regarding the ingredients that are typically added when creating DIY glass fiber concrete, they include the following:

1. Plasticizing additives. Contribute to increasing plastic properties without losing strength.
2. Air-extracting components. Necessary to increase resistance to negative temperatures. They also increase the service life, mobility and alkali resistance of the structure.
3. Additives for accelerating setting. Introduced into the composition at an ambient temperature of 10 °C.
4. Anti-frost additives. Maintain the mixture in a liquid state, which provides the right conditions for hardening.
5. Water repellents. Responsible for hydrophobic properties.
6. Setting retarders. They are an important additive when mixing the solution in the hot period.

Advantages and disadvantages of the material

You need to weigh the material’s advantages and disadvantages in order to comprehend what glass fiber concrete is, how it differs, and its intended applications.

1. Resistance to compressive and tensile loads.
2. Reduced weight, which reduces the overall load on the foundation of the building.
3. Resistance to biological or atmospheric precipitation, fire resistance.
4. Increased plastic characteristics and rapid hardening.
5. Resistance to corrosion processes.
6. Wide selection of products and manufacturers.
7. High resistance to negative temperatures.
8. Compliance with environmental standards and regulations.
9. Affordable cost.

Apart from its advantages, the material also has disadvantages. Its fear of an alkaline environment is its first drawback, but this is offset by the glass fiber in the composition. Second, quick application is necessary because the mixture hardens quickly.

Manufacturing technology

Once you have a thorough understanding of glass fiber concrete’s attributes and uses, you can move on to producing the material on your own.

Variability of equipment

Building materials based on composite raw materials are produced using various technologies. Preparing the necessary tools and materials in advance is necessary for creating glass fiber concrete.

1. A mixer that mixes the main components.
2. A pneumatic gun for spraying premixes.
3. A pump unit with a peristaltic pump.

In order to ensure high-speed mixing of the components during the manufacturing process, the mixer needs to have a high shear force. You can use a small water-to-cement ratio to produce a homogenous solution free of lumps and contaminants with the aid of such a unit.

To ensure that the solution is supplied consistently, a mortar pumping station is required. The components are to be sprayed pneumatically by the pneumatic gun.

It might be required to use extra equipment, like a compressor and spring rollers, to automate the process.

To produce products, the craftsman must also set up specific molds. Polyurethane is used to create flexible structures, while plastic or laminated chipboard is used to create hard ones.

The following details should be taken into account when selecting a material to make molds:

1. Polyurethane. It is especially popular, since flexible molds for the production of fiber-reinforced concrete products are created on its basis. The material is famous for its long service life and can hold elements with negative edges. Before use, the mold must be lubricated.
2. Fiberglass. In demand in the production of fiberglass concrete with any texture. A fiberglass mold is reliable, durable and easy to use. But if you need to create products with negative angles, this option cannot be considered.
3. Steel. It is used to manufacture standard block shapes on an industrial scale.
4. Wood. Forms made from different types of wood are affordable, but require preliminary processing.
5. Silicone. In appearance, these forms are similar to polyurethane structures. They are characterized by flexibility and ease of use.

If you wish to produce glass fiber concrete on your own, you will need to weigh the advantages and disadvantages of the forthcoming work before making any significant financial commitments to equipment selection.

Main technologies

The features and particulars of the various technologies used to produce glass fiber concrete vary. The most popular technique is pneumatic spraying, which involves applying fiberglass and a cement-and-sand mixture to the form or surface using a specialized gun.

The fiber is blended with other ingredients and additives at the outlet to produce a uniform consistency. The expensive equipment is one of the technology’s drawbacks. The ability to produce large amounts of material industrially is an advantage.

Additionally, builders employ the highly sought-after technique of pneumatic premix spraying, which is a relatively new technique. When building small or medium-sized structures, it is in demand. Additionally, you can apply a plaster coating by using the technology.

Since pre-cut fiber is added to the composition and the final mixture is fed into the gun and sprayed, the method’s general idea and specifics are similar to those of the previous version.

The pre-mixing method of production stands out for being simple to use at home. Since all of the ingredients are manually mixed or combined in a concrete mixer, the technology is incredibly accessible and straightforward.

Fiberglass is added to a cement-sand mixture that has first been prepared. Since the consistency is marked by rapid hardening, high speeds of formation are applied to the mixture after it has been thoroughly mixed. The technology is applied to modest task volumes.

DIY production

Pre-mixing the components is a better way to quickly create glass fiber concrete for private construction needs. However, before you do this, there are a few pointers and subtleties to consider that will affect the final product:

1. Particular attention should be paid to preparatory work, when components are selected and mixed. The success of the process depends on the correctness of your actions at the preparatory stage.
2. The optimal proportions of sand and cement are 1 to 1. But these values ​​​​are adjusted taking into account the requirements of the project and such features as dimensions, scope and type of product.
3. The water level in the mixture should be minimal, while the solution should remain mobile. The volume of liquid is determined by a lot of factors. Including: the degree of water demand of sand, the brand and properties of cement, the required strength characteristics of the future product.
4. The concentration of fiber is selected empirically. The optimal reinforcement level varies from 3 to 6%.
5. All components require thorough mixing, and the finished mixture is applied in thin layers and pierced. If this is not done, it will be problematic and even impossible to get rid of air in the future.
6. To compact the solution, you will need to use vibration equipment.
