Buy AAC Blocks Online: Top Deals On Durable And Lightweight Construction Materials

In modern construction, strength combined with efficiency defines successful projects. Materials that have gained preference include AAC blocks or Aerated Autoclaved Concrete blocks. These blocks have led to a quantum change in the way structures are being made, allowing for lightweight yet strong and rigid alternatives to the commonly used brick and concrete blocks.

What Are AAC Blocks?

AAC blocks are a type of light, precast, and autoclaved concrete product mainly for the construction of walls and partitions in buildings. The term "autoclaved" is a process wherein the blocks undergo curing under steam pressure, leaving them with a cellular structure. Thus, these endow the blocks with special attributes such as high strength, thermal insulation, and soundproofing; therefore, extremely useful in the construction of residences and commercial purposes.

Composition Of AAC Blocks

Raw materials used in the production of aerated autoclaved concrete blocks include:

• Cement
• Lime
• Silica, as sand
• Water
• Aluminum powder to introduce air bubbles

This mixture is then cast into molds and allowed to expand into a cellular structure, which provides its light yet robustness. After these blocks are produced, they are then transferred into an autoclave (large pressure chamber), in which the strength and structural properties are developed with the high heat and pressure applied in this autoclave.

Advantages Of AAC Blocks

Now that we have identified the major advantages of AAC blocks in construction works, let's now discuss the sizes and prices of these blocks in the following.

• Light in Weight: AAC blocks weigh less than those made of regular bricks and concrete blocks. The lightness reduces the loads carried out on the structures. This generally provides for better safety on the buildings and makes handling easier during transport in construction.
• Insulation Against Heat: One of the most important positive attributes of AAC blocks is thermal insulation. In other words, AAC blocks tend to have superior resistance to thermal flow. Air pockets within blocks create a more resistant barrier to heat transfer into buildings, sustaining an almost temperature-neutral environment, which reduces the usage of artificial systems for heating or cooling.
• Resistance To Fire: AAC blocks are fire-resistant, providing up to 4 hours of fire protection depending on their thickness. This is a very important consideration, especially for high-rise buildings or areas where fire safety is critical.
• Sound Insulation: The cellular structure of AAC blocks ensures excellent soundproofing. The air pockets within the blocks help to absorb and dampen sound, making them ideal for residential and commercial applications where noise reduction is needed.
• Eco-friendly: Compared with clay bricks, AAC block production is relatively more environmentally friendly. They have low waste, lesser CO2 emissions, and are made from raw natural materials. Also, the energy efficiency of the buildings where AAC blocks would be used would reduce carbon footprint significantly.

AAC Blocks Size And Price

AAC Block Sizes

The different sizes of AAC blocks make them compatible with various types of construction, including load-bearing walls, partition walls, and flooring. However, the size may differ between manufacturers, but here are common sizes in the market:

The length is normally 600 mm for most of the AAC blocks, while width and height depend on the specific application of the block. Thinner blocks are usually used for non-load-bearing partition walls, and the thicker blocks are used for load-bearing walls or other structural elements which require support.

AAC Block Price

The cost of AAC blocks varies mainly on the size, density, and brand. From one place to another, in terms of quantity sold, or based on the supplier's quotations, its prices may vary. But for general guidance, here's an approximate AAC block price:

• Note: Prices will also depend on location, manufacturer and volume ordered, so it would be best to ask for quotes from different companies to get a good price quotation for your exact needs.

Other Factors That Could Influence The AAC Block Price

• Block Size/Thickness: Higher blocks or of greater thickness attract higher prices.
• Supplier Location: The local supplier might quote less as transportation charges would be minimal.
• Quantity: Order in bigger lots to qualify for a discount on bulk orders.

Other Significant Factors

1. AAC Block Density

Density is the other critical factor in deciding the strength and thermal insulating properties of AAC blocks. Blocks are divided into three types based on their density.

• Low Density (600-800 kg/m³): These are used in partition walls and non-load-bearing applications.
• Medium Density (800-1000 kg/m³): These are best suited for load-bearing walls and interior partitioning.
• High Density (1000-1200 kg/m³): It has been developed for structural members such as base walls, high-rise buildings, and so on carrying load function.

AAC blocks with higher densities are stiffer and more costly, but consequently more resilient against external perturbations (e.g., pressure, fire, noise).

2. Workability And Ease of Installation

Another significant benefit of the AAC blocks is the simplicity of the installation. They are easy to trim, form, and manipulate, thus a shorter construction time and labour costs are realized. Their portability further enhances the ease of their carrying and coordination on-site. For AAC block installations, proprietary adhesives or thinned-bed mortar are commonly employed instead of Portland cement due to the requirement for strong bonds and to avoid cracking in the joints.

3. Durability And Maintenance

AAC blocks are also very sturdy and weatherproof and are mold, pest and water resistant. Problems unique to the use of regular bricks or concrete blocks (i.e., cracking or deterioration due to environmental stresses) are not present. That is, the lifecycle maintenance of AAC blocks is lessened in the long term.

4. Environmental Impact

The production process of AAC blocks has a much lower environmental impact compared to traditional bricks made from clay, which involves mining and burning. Due to the nature of AAC blocks made with combinations of eco-friendly raw materials and minimal waste generation, AAC blocks may offer an environmentally sustainable option for sustainable construction applications.

How To Install AAC Blocks?

AAC blocks are simple to install because they are relatively lightweight and are of relatively uniform size. Following is a detailed description of the process of installing AAC blocks.

• Preparation: Check that the base or platform on which the blocks will be situated is flat and free of debris, before the start of the installation. Setting up the work area has to be done by removing debris and rough surfaces to ensure that the number of blocks is properly aligned. There may be cases where, for the mortar to bond sufficiently with the substrate below, a bonding agent needs to be applied.
• Cutting: AAC blocks can be cut quite easily through a diamond-pointed saw or tools designed for aerated concrete. It is possible to modify due to cutting the size of the blocks, to adapt to the needs of the project. Clean cuts are to be made to get a proper fit for the installation.
• Laying Blocks: Coat the surface with a thin layer of mortar or adhesive and attach the first row of blocks. Blockings should be plumbed and lined up with the wall to create a straight wall. AAC blocks may be laid in a block pattern, similar to brickwork used in conventional masonry.
• Jointing: Grout (mortar or adhesive) should then be inserted at the gaps between blocks. Make sure the mortar is uniformly spread out so it forms a good bond between the blocks. Joints must be sealed properly to preclude voids through which air or water leaks can occur.
• Finishing: After the blocks are fixed in turn, finish the wall with plastering, painting or other surface finish corrections. Apart from improving wall aesthetics, it can also serve as a protective coating for the wall against weather effects.

Advantages Of AAC Block Installation

• Speed: AAC block laying is faster than traditional bricklaying, consisting mostly due to the low weight and ease of mechanization. This means a decrease in project duration, in turn leading to the faster completion of the project and a decrease in labour cost in the end.
• Less Labor: Because they are lighter, AAC blocks can be easily moved and handled to a site which decreases the number of workers required to complete an installation. The result is labour cost decrease and project schedule shortening.
• Accuracy: Universal size and geometry of AAC blocks provide perfectly straight lines and levelled walls. This level of accuracy in block size minimizes the need for large-scale adaptation at the time of installation and leads to good-quality walls with minimal need for finishing operations.
• Reduced Waste: Because AAC blocks can be cut and routed relatively simply, there is less material waste in the use of AAC blocks compared to other building materials. This may also be applied to reduce costs and get more environmentally friendly construction.
• Cost Efficiency: Even if the per AAC block initial price can be considered quite slightly higher than the price of standard bricks, their very good thermal and acoustic insulating properties give rise to greatly increased energy bills over time. Moreover, they are very easy to install which reduces labor cost and is thus an economical solution to the budget of the entire project.

Conclusion

In conclusion, AAC blocks offer numerous benefits, including lightweight construction, thermal insulation, fire resistance, and soundproofing, making them an excellent choice for modern construction projects. The price of AAC blocks varies based on size, density and location of the supplier, but they are, for the most part, also quite cheap and economical in the longer term due to their energy saving and strength.

If you're planning to incorporate AAC blocks into your next building project, then carefully consider the size and the density of the block, which will most likely work for you, and don't forget to take advantage of the economies of scale of ordering higher quantities.
