Ventilation from expanded clay concrete blocks

In order to keep indoor spaces comfortable and healthy, ventilation is essential. In addition to preventing moisture buildup and lowering the chance of mold growth, proper air circulation guarantees a supply of fresh air. The living conditions within a building made of expanded clay concrete blocks can be greatly improved by including an effective ventilation system.

Expanded clay concrete blocks are widely used in contemporary construction because of their superior thermal insulation, sturdiness, and portability. The clay used to make these blocks is heated to a point where it expands, giving it a porous structure. This porosity helps the material move air more easily and adds to its insulating qualities, which makes it a good option for structures that need good ventilation.

Strategic planning is required when implementing ventilation in buildings built with expanded clay concrete blocks. Because the blocks are porous, air can pass through the material and contribute to natural ventilation. Still, other steps are required to maximize air flow throughout the building, like adding ventilation ducts and making sure windows and vents are positioned correctly.

To improve air movement, mechanical systems can be integrated in addition to natural ventilation. When using expanded clay concrete blocks, heat recovery ventilators (HRVs) and energy recovery ventilators (ERVs) are common options. In addition to preserving energy efficiency, these systems exchange stale indoor air with fresh outdoor air, enhancing the comfort and health of the interior environment.

All things considered, expanded clay concrete blocks present a flexible option for contemporary building, fusing the advantages of good ventilation with structural qualities. Builders can design spaces that not only withstand the test of time but also offer a healthy living environment by comprehending and utilizing these properties. Integrating adequate ventilation into structures using these blocks, whether for residential or commercial use, is a step toward sustainable and comfortable living.

Definition

In a building structure, a ventilation block is an independent product. possesses a variety of ventilation duct types. The load-bearing walls are fixed to the ventilation system with cement mortar or a welding machine. This design provides an efficient air exchange system.

Features

The following types of expanded clay concrete ventilation blocks exist:

Expanded clay concrete blocks have the following benefits for ventilation:

• the use of such blocks can provide natural ventilation of buildings and structures without the use of air ducts and other technical devices;
• are capable of forming a separate natural ventilation system, without the need to control and adjust it.

Expanded clay concrete ventilation blocks have the following drawbacks:

• the need for preliminary calculations when drawing up a plan for buildings and structures, which entails the expenditure of funds to attract a specialist;
• the ability to provide simple ventilation;
• do not replace air cooling devices.

Where are they used?

Expanded clay concrete ventilation is useful in the following situations:

• chimneys;
• fence posts;
• for ventilation of a public building;
• ventilation ducts;
• sanitary facilities and kitchens;
• permanent formwork.

For instance, extended clay concrete chimneys offer the following benefits:

• ease and speed of installation of the chimney;
• reducing the load on the base of the chimney;
• the presence of an additional block for a large amount of ventilation;
• the chimney can be installed in the walls, which allows you to save the area of ​​​​the room.

The method of sintering the solution under intense pressure is applied to expanded clay blocks. The chimney blocks have strength properties and a long service life thanks to this technology.

Standard sizes and marking

Products made of expanded clay are labeled based on the following factors:

• type;
• type of material;
• resistance of concrete to an aggressive environment;
• size;
• seismic resistance;
• standard designations of product manufacture.

As a result, products are identified by the following letters: L for lightweight concrete; H for normal resistance; P for reduced resistance; O for especially low resistance; and C for seismic resistance. The corresponding numbers are used to mark the products’ height and length. Brands differentiate the following sizes of expanded clay ventilation elements:

• BV-28 has a length, width, height of 278 centimeters, 80 centimeters, 40 centimeters respectively;
• BV-29 – 283 cm, 80 cm, 40 cm;
• BV-30 – 298 cm, 80 cm, 0 cm;
• BV-31 – 131 cm, 80 cm, 40 cm;
• BV-33 – 328 centimeters, 80 centimeters, 40 centimeters.

There are additional concrete grades and sizes that go along with them.

Laying technology

Calculating the characteristics of buildings and other structures is the first step in laying ventilation blocks. It is worthwhile to invite a qualified architect for this. The action plan will guarantee the ventilation system’s effectiveness and lower material costs. This is how ventilation block technology is used:

• Work begins with preparing the workplace, for this, remove debris that can form distortions and increase the strength of the connection of two different materials.
• After which the working surface is moistened and closed with plugs that will protect the ventilation ducts from the solution.
• Next, take water, one part cement and three parts sand and make a solution. For more correct proportions and high-quality material, use a mixture made at the factory.
• After thoroughly mixing the components of the mixture, it is applied to the template.
• Stretch the cement composition along the cross-section using a trowel.
• After the rigger inspects the block and gives permission for lifting, immerse it in the lifting mechanism.
• The ventilation block at the installation site is checked by fitters for compliance of the holes with the lower sections.
• For the evenness of the structure, its vertical is checked and, if necessary, the location of the product is adjusted.
• Grasp the embedded elements of the structure to the walls using welding. It is important to maintain even fixation of the block to prevent its displacement.
• At the end of laying the ventilation blocks, process and seal the seams using a trowel.

Using expanded clay concrete blocks for ventilation is a good way to keep the air quality inside your home healthy. These blocks are perfect for building walls with integrated ventilation systems because they are not only long-lasting but also provide excellent thermal insulation. These blocks reduce humidity and inhibit the growth of mold by allowing a controlled exchange of indoor and outdoor air thanks to the expanded clay’s inherent porosity.

The environmental friendliness of expanded clay concrete blocks is one of their main benefits. They are an eco-friendly building material that improves energy efficiency because they are made of natural clay. These blocks’ lightweight design also makes construction easier, which speeds up and lowers the cost of ventilation system installation.

Expanded clay concrete blocks can provide ventilation, which can improve living areas’ general comfort and health. In order to rid indoor environments of pollutants, allergens, and excess moisture, proper ventilation is essential. Homeowners can accomplish balanced airflow with these blocks without sacrificing structural integrity or insulating qualities.

To sum up, expanded clay concrete blocks present a flexible and eco-friendly solution for incorporating ventilation into architectural plans. Because of their inherent qualities, they are a great option for promoting energy-efficient building techniques and fostering healthier interior spaces. Both homeowners and builders can benefit from increased comfort and better air quality by selecting these blocks.

Expanded clay concrete blocks provide strong structural advantages and an effective means of enhancing indoor air quality through ventilation. By allowing air to pass through them, these blocks help control the humidity and temperature inside buildings. Because there is less need for mechanical systems thanks to this natural ventilation, energy expenses and environmental effect are reduced. Furthermore, expanded clay balances practicality and performance, making it an excellent material for both residential and commercial construction due to its lightweight and durability.
