AAC Blocks Size 9″x5″x3″

Description:

Autoclaved Aerated Concrete (AAC) Blocks are lightweight, precast building materials made from a mixture of cement, lime, sand, water, and an aerating agent (aluminum powder). This mixture creates a cellular structure, which is then cured under high-pressure steam in an autoclave to form durable, strong, and energy-efficient blocks. The 9″x5″x3″ size of AAC blocks is typically used for non-load-bearing or partition walls and applications requiring medium thickness. They are highly regarded for their excellent thermal insulation, fire resistance, soundproofing, and environmental benefits.

Technical Specifications:

• Dimensions:

  • Length (L): 9 inches (225 mm)
  • Width (W): 5 inches (125 mm)
  • Height (H): 3 inches (75 mm)

• Material Composition:

  • Cement (Portland cement)
  • Lime
  • Silica Sand
  • Water
  • Aluminum powder (used to create the aerated structure)

• Density:

  • The typical density for 9″x5″x3″ AAC blocks ranges from 500 to 800 kg/m³, depending on the product grade and the aerating agent used.

• Compressive Strength:

  • Compressive strength varies between 3.5 MPa (megapascals) and 7 MPa for standard blocks, and can go up to 10 MPa for high-strength versions, making it suitable for non-load-bearing walls, partitions, and lightweight construction.

• Thermal Insulation:

  • AAC blocks offer excellent thermal insulation, with a thermal conductivity in the range of 0.11 to 0.16 W/m·K.
  • This helps to reduce energy costs by maintaining stable indoor temperatures and improving energy efficiency in buildings.

• Fire Resistance:

  • AAC blocks are highly fire-resistant and can withstand temperatures of up to 1,200°C (2,192°F) without significant degradation, making them ideal for fire-rated walls.
  • Fire rating: Typically, AAC blocks can offer up to 4 hours of fire resistance.

• Water Absorption:

  • Water absorption for AAC blocks typically ranges from 15% to 20% by weight. While they are more water-resistant than many other materials, additional waterproofing may be necessary for areas with high moisture exposure.

• Sound Insulation:

  • Due to their porous structure, AAC blocks provide excellent sound insulation. The sound reduction is typically around 45 dB, depending on the thickness of the wall and the application.

• Weight:

  • A 9″x5″x3″ AAC block weighs approximately 6 to 8 kg (13 to 18 lbs), depending on the density and moisture content of the material. Their lightweight nature reduces handling and transportation costs.

• Dimensional Accuracy:

  • AAC blocks are known for their precise dimensions, offering consistent quality and uniformity, which allows for faster and more efficient construction.

• Environmental Impact:

  • AAC blocks are an eco-friendly option, made from natural raw materials and using an energy-efficient manufacturing process. They produce fewer greenhouse gases compared to traditional concrete blocks or bricks.

Advantages of AAC Blocks:

• Lightweight: Easy to transport, handle, and install, reducing labor costs and construction time.
• Energy Efficient: Excellent thermal insulation, helping maintain consistent temperatures and reducing the need for heating or cooling systems.
• Fire Resistant: AAC blocks provide superior fire resistance, making them ideal for safety-conscious constructions, including fire-rated walls and fireproofing.
• Soundproofing: Due to their cellular structure, they offer superior sound insulation, reducing noise transmission in buildings.
• Sustainable and Eco-friendly: Made from natural, non-toxic materials, AAC blocks are a sustainable construction solution with minimal environmental impact.
• High Durability: AAC blocks are resistant to pests, moisture, and environmental degradation, contributing to long-lasting structures.

Applications:

• Partition Walls: Ideal for creating internal non-load-bearing walls or room dividers in both residential and commercial buildings.
• Non-load-Bearing Walls: Perfect for constructing walls that do not carry significant structural weight, such as internal dividing walls in homes or offices.
• Fire-rated Construction: Due to their high fire resistance, AAC blocks are suitable for creating fire-rated partitions, ceilings, and other structural elements.
• Soundproofing Applications: AAC blocks are effective for reducing noise transmission, making them an excellent choice for soundproofing between rooms or in areas with high noise levels.
• Energy-Efficient Buildings: AAC blocks contribute to the creation of energy-efficient structures due to their excellent insulation properties.

Conclusion:

The 9″x5″x3″ AAC block is an ideal solution for partition walls, non-load-bearing applications, and energy-efficient buildings. With its combination of light weight, high thermal insulation, fire resistance, and durability, AAC blocks offer significant advantages over traditional building materials, making them an excellent choice for modern construction. Their eco-friendly properties and cost-saving potential further enhance their appeal in both residential and commercial projects.
