11 Benefits of Using AAC Blocks for Your Next Project

The construction industry is currently witnessing a transition from conventional brick usage to adopting Autoclaved Aerated Concrete (AAC) material in its projects. This shift is fueled by the increasing need for lightweight, durable construction materials and the growing emphasis on eco-friendly building practices. 

In recent years, AAC blocks have garnered significant favor due to their numerous advantages, such as their superior strength, durability, and lightweight. Due to its multiple benefits over red clay bricks, it is estimated that AAC concrete’s market size will reach $25.5 billion with a CAGR of ~6% by 2025.

This article delves into various additional benefits that position AAC blocks as the preferred option for construction endeavors. Before exploring these advantages, it is important to provide a brief overview of what AAC blocks entail.

What are AAC blocks?

AAC blocks are precast foam concrete building blocks that comprise materials like cement, sand, lime, quartz, calcined gypsum, and water.

These components are shaped into blocks and autoclaved under tremendous pressure. AAC blocks are manufactured from non-biodegradable materials, enhancing resistance to mold and contributing to cleaner and more durable interiors and adding a value to green building solutions.

11 Cost-Cutting Advantages of AAC Blocks:

1. Environment Friendly

Embracing AAC blocks in construction represents a significant step towards a more sustainable future, thanks to its environmentally friendly and non-toxic qualities that generate zero waste during the construction process. Constructed using 70% fly ash which is a national waste, AAC blocks become preferable compared to red clay bricks which contribute to the depletion of topsoil, hindering favorable conditions for vegetation.

2. Flexibility and Versatility

AAC blocks can be manufactured in a variety of sizes, designs, and strengths to align seamlessly with the architectural specifications of your building. When compared to red clay bricks and solid concrete blocks, working with AAC blocks facilitates easier plumbing and chiseling. This increased versatility makes AAC blocks a preferred choice for both builders and end users alike.

3. Thermal Insulation

Renowned for their thermal conductivity, AAC blocks contribute to maintaining a comfortable indoor environment, keeping interiors warm in cold weather and cool in hot conditions. This characteristic has a direct impact on reducing energy consumption related to air conditioning, resulting in potential cost savings of up to 30%. This positions AAC blocks as a more energy-efficient and cost-effective choice compared to other building materials.

4. Earthquake Resistant 

One of the main advantages of using AAC blocks is its lightweight with the highest strength-to-weight ratio. With a density ranging from 550 to 650 kg/m³, AAC blocks are lighter than water and possess a compressive strength of 4 N/mm². 

Due to their lightweight, AAC blocks become a perfect choice for high seismic zones and offer optimal earthquake resistance. 

5. Reduced Construction Time

Using AAC blocks can accelerate your construction time and help with project timelines. Their lightweight composition and interlocking design contribute to the swift and straightforward installation. This efficiency translates to noteworthy cost savings and faster completion of projects. 

6. Fire and Sound Resistant

AAC blocks are known for their exceptional fire resistance, reportedly withstanding flames for a minimum of 6 hours and up to temperatures of 1200 degrees Celsius. Their superior fire rating falls within the range of 4-6 hours. AAC blocks boast a melting point exceeding 1600 degrees Celsius due to their cellular structure which contributes to this impressive fire resistance. 

AAC blocks carry Sound Transmission Class (STC) of approximately 45 db making it a perfect solution for wall construction. The excellent sound absorption of AAC blocks results from their porous structure during the manufacturing process.

7. Energy Efficient

AAC blocks ensure a consistently warm interior during winter and a cool environment in the summer months. During construction, the formation of hydrogen in small pockets contributes to the enhanced insulation properties of AAC blocks. This insulation quality is a key reason why AAC blocks are utilized in construction across various geographical locations.

8. Availability

The easy availability of AAC blocks is a major advantage it brings to the construction industry. Seasonal changes make the availability of red bricks a challenge during construction, especially during monsoons as they catch moisture easily. 

9. Pest Resistant

AAC blocks effectively deter common nuisances such as termites and rodents due to their composition of inorganic materials. Additionally, the air pores and pockets within AAC blocks make them soundproof and moisture-resistant, keeping out pests and preventing moisture infiltration.

10. Design Flexibility

As a number one choice among Architects, AAC blocks offer the design flexibility to cut, shape, and mold to craft intricate designs. They can be easily tailored to match different architectural styles and design preferences. 

11. Cost-Efficiency

The long-term advantages surpass the initial costs associated with AAC blocks. The time saved in construction, decreased labor expenses, energy efficiency, and low maintenance requirements make AAC blocks a financially sensible option.

Choosing the Right AAC Block Company

From energy efficiency to design flexibility, especially cost savings, AAC blocks are revolutionizing the construction industry with their wide range of benefits. 

Opting for AAC blocks from a good AAC Block company for your upcoming projects can lead to the creation of a structurally robust, eco-friendly, and economically efficient building that withstands the test of time.
