What are lightweight concrete blocks?

Lightweight Concrete Block is a lightweight concrete construction material. Made of cement, sand, volcanic rock, fly ash, and air foaming agents. This causes the brick to contain several microscopic air bubbles. As a result, it's 60-70% lighter than regular bricks.

What are the benefits of using lightweight concrete blocks?

1. Lightweight: 

Lightweight concrete blocks are significantly lighter than traditional bricks and concrete, making construction faster, easier, and more cost-effective.

2. Thermal insulation: 

The air pockets within lightweight concrete blocks act as a thermal insulator, helping to keep homes cooler in the summer and warmer in the winter, which can lead to significant energy savings.

3. Sound absorption: 

Lightweight concrete blocks have excellent sound absorption properties, making them ideal for creating quiet and peaceful living spaces.

4. Fire resistance: 

Lightweight concrete blocks are highly fire-resistant, providing an added layer of safety for your home.

5. Cost-effectiveness: 

Lightweight concrete blocks can help reduce overall construction costs by minimizing the need for labor, materials, and energy.

Types of lightweight concrete blocks

There are two main types of lightweight concrete blocks:

These blocks are produced through a high-pressure steam curing process, resulting in a strong and durable material suitable for load-bearing walls.

These blocks are not cured under high pressure, making them less dense and more suitable for non-load-bearing walls such as partitions.



Things to consider when using lightweight concrete blocks:

  • Lightweight concrete blocks are susceptible to moisture absorption, so it's important to apply a water-resistant sealant to the surface of the blocks.
  • Specific materials and tools, such as lightweight concrete mortar, reinforcement bars, and mesh, should be used when constructing walls with lightweight concrete blocks.
  • It's essential to choose the right type of lightweight concrete block for your specific construction project.



Conclusion

Lightweight concrete blocks offer a compelling alternative to traditional building materials, providing numerous benefits such as speed, cost-effectiveness, energy efficiency, thermal insulation, sound absorption, and fire resistance. By choosing the right type of lightweight concrete block and following proper construction techniques, you can build a durable, comfortable, and energy-efficient home.

Lightweight Concrete Block is a lightweight concrete construction material. Made of cement, sand, volcanic rock, fly ash, and air foaming agents. This causes the brick to contain several microscopic air bubbles. As a result, it’s 60-70% lighter than regular bricks.

  1. Lightweight: makes construction quick and simple. Reduce time and labor costs.
  2. Thermal insulation: The air bubbles within the lightweight brick serve as heat insulators. Helps keep the house cool and pleasant, lowering energy expenditures.
  3. Sound absorption: Lightweight bricks can effectively absorb sound. helps keep the house peaceful. Suitable for relaxing.
  4. Fireproof: Lightweight bricks can endure fire for more than 4 hours, making your home safer.
  5. Save money: Lightweight bricks reduce materials, labor, and electrical expenses.

There are two primary types of lightweight bricks:

  1. Autoclaved Aerated Concrete (AAC):  lightweight brick is made using a high-pressure steam drying method. Increases the brick’s strength. Suitable for building projects requiring strength and durability, such as weight-bearing walls.
  2. Non-Autoclaved Aerated Concrete (NAAC): is a lightweight brick type that is produced without steam treatment. The brick material is less dense than AAC, making it ideal for high-speed construction activity. Save money on things like room partition walls.
  • Lightweight brick is a material that readily absorbs moisture. As a result, you should apply or spray a waterproofing solution onto the wall surface.
  • When constructing walls using lightweight bricks, utilize appropriate materials and equipment, such as lightweight brick mortar. and strengthened steel mesh.
  • You should research the facts and select lightweight bricks suitable for construction activity.

Lightweight bricks are suitable for many types of construction work such as

  • Residential house
  • Commercial building
  • Factory
  • Warehouse
  • Room wall
  • Load-bearing wall

The standard price of lightweight brick is approximately 28-80 baht per brick, depending on the size. Transportation distance and brand
