Autoclaved aerated concrete block price

Types of autoclaved aerated concrete blocks

Aerated concrete blocks are developed from commonly used raw materials such as lime, sand, cement, water, and aluminum powder as an expanding agent. AAC is a lightweight, high-performance building material that offers several advantages such as workability, cost-effectiveness, strength, and eco-friendliness. Depending on the needs of a project, different types of AAC blocks are available for use in construction.

The three main categories for classifying AAC blocks are functional use, physical composition, and production techniques.

• Functional Use: According to functional use, AAC is separated into load-bearing, non-load bearing internal, and non-load bearing external categories. Load-bearing blocks are structural elements that support loads in a building. Non-load-bearing internal blocks are partitions that can be used to create internal walls but do not carry any loads. Non-load-bearing external blocks are used to create external walls and need to be used together with load-bearing elements.
• Physical Composition: The physical composition of AAC blocks also sets different types apart. While all blocks are made from the same material, panel products are large-format blocks that are suitable for use in constructing large areas. Slab products, on the other hand, are more suitable for creating enclosing elements, while lintels are used for creating structural support over openings like doors and windows.
• Production Techniques: The production techniques set different kinds of AAC blocks apart. Traditional AAC blocks are made from a mixture that is autoclaved in a high-pressure steam environment. Fly ash-based AAC blocks are produced from fly ash, a by-product of coal combustion in power plants. This not only recycles industrial waste but also reduces the carbon footprint of the blocks. VERMITECH blocks, on the other hand, are produced from a mixture that includes vermiculite, an insulated mineral that helps to increase the thermal insulation of the block.

Specification & maintenance

Maintenance is crucial to ensure the long-lasting performance and functionality of autoclaved aerated concrete blocks. Regular inspections should be carried out to identify any signs of damage, such as cracks, voids, or degradation of the surface. Prompt repairs should be made to address any issues and maintain the integrity of the AAC blocks.

It is essential to keep the AAC blocks clean and free from debris or dirt accumulation. Gentle cleaning methods, such as low-pressure water washing or soft brushing, should be employed to avoid damaging the surface. Additionally, the use of mild detergents or AAC-specific cleaners can help remove stubborn stains.

Proper sealing is also a critical aspect of AAC block maintenance. Applying a breathable water repellent sealer can help protect the blocks from moisture penetration and surface staining. Regular sealing, depending on the exposure conditions, can enhance the durability and longevity of the AAC blocks.

Consideration should also be given to the surrounding areas of the AAC blocks. Proper drainage systems should be in place to prevent water pooling near the blocks, reducing the risk of moisture-related issues. It is beneficial to maintain adequate airflow and ventilation around the AAC blocks to avoid excessive humidity and moisture buildup.

Implementing a routine inspection and maintenance schedule can help ensure the long-lasting performance and structural integrity of the autoclaved aerated concrete blocks. Following the manufacturer's guidance and seeking professional assistance for repairs or maintenance is always recommended.

How to choose autoclaved aerated concrete blocks

• Quality

  It is better to check the quality of AAC blocks before buying them in bulk. Examine the manufacturing process and the quality control standards to ensure they meet the necessary specifications and certifications.

• Size and structural features

  The size of an autoclaved aerated concrete block may vary according to the scope of the project. When selecting the dimensions in a cost-effective manner, one should determine the total number of blocks required for the project. Larger blocks may cover more area with fewer units, while smaller blocks may provide better control for complex designs.

  Another thing to consider is the structural features of the blocks. Certain shapes or configurations may be more suitable for specific projects, such as load-bearing walls, non-load-bearing walls, or multi-directional walls. Ordering blocks with the appropriate structural features can help reduce the need for additional adjustments on-site, saving time and labor costs.

• Transport costs

  Cover a larger area with fewer units and often weigh less than traditional concrete, which can lower transport costs. However, the overall cost of transportation will depend on various factors, such as the distance to the delivery location, the weight and volume of the blocks, and the transportation method.

  When considering transport costs, it is essential to recognize that AAC blocks are often more cost-effective to transport than heavier, denser building materials. Their lighter weight and higher volume-to-weight ratio can result in lower fuel consumption and lower transportation emissions.

• Long-term costs

  Choosing high-quality AAC blocks may incur higher initial costs. However, the durability, energy efficiency, and performance of AAC blocks can lead to significant long-term cost savings in reduced maintenance, operating expenses, and life-cycle costs.
