Hollow Block Price in Bangladesh: Everything You Need to Know
Hollow blocks are an essential construction material widely used in Bangladesh for their strength, durability, and cost-effectiveness. Whether you’re building a home, a commercial space, or a large-scale infrastructure project, understanding the hollow block price in Bangladesh and their properties is crucial for making informed decisions.
In this guide, we will explore everything you need to know about hollow blocks, including their sizes, compressive strength, types, and applications. We will also discuss the price of hollow blocks in different regions like Chittagong and review the benefits and disadvantages of using hollow blocks in construction projects.

What Are Hollow Blocks?
Hollow blocks are precast concrete blocks that are primarily used for building walls and structures. These blocks are made by casting concrete around a hollow core, which reduces their weight and increases their thermal and acoustic insulation properties. Concrete hollow blocks are more efficient and cost-effective compared to traditional solid bricks.
The compressive strength of hollow blocks varies, and it plays a significant role in their suitability for different construction purposes. For example, standard compressive strength of hollow blocks typically falls in the range of 5-10 N/mm².
Hollow Block Price in Bangladesh
The price of hollow blocks in Bangladesh can vary depending on several factors, including the size, compressive strength, and the region where you purchase them. In major cities like Chittagong, the cost of hollow blocks tends to be slightly higher due to transportation costs and demand fluctuations. However, hollow blocks are generally affordable and offer a long-term value for construction projects.
Prices for hollow blocks in Bangladesh typically range from BDT 40 to BDT 70 per block. Factors such as size, material quality, and factory location can influence the exact pricing.
390mm*190mm*90mm (15.5 * 7.5 * 3.5 inch) | Hollow (3 Holes) | 40 tk |
390mm*190mm*140mm (15.5 * 7.5 * 6 inch) | Hollow | 52 tk |
400mm*190mm*100mm (16 * 7.5 *4 inch) | Hollow (2 holes) | 42 tk |
390mm*190mm*190mm (15.5 * 7.5 * 7.5 inch) | Hollow | 68 tk |
Common Hollow Block Sizes in Bangladesh
When selecting hollow blocks for a construction project, it’s important to consider the size of hollow blocks that best suits your needs. Common sizes available in Bangladesh include:
- 6 inches x 7.5 inches x 16 inches
- 4 inches x 7.5 inches x 16 inches
- 7.5 inches x 7.5 inches x 16 inches
These sizes can vary slightly depending on the manufacturer and local regulations. The appropriate size of hollow block depends on the thickness of the wall and the required strength for the building.
Benefits of Using Hollow Blocks
There are several reasons why hollow blocks are preferred for construction in Bangladesh:
1. Lightweight Construction
Hollow blocks are lighter than traditional bricks, making them easier to handle and transport. This also reduces the overall weight of the structure, which can be advantageous in areas with weak soil conditions.
2. Thermal and Acoustic Insulation
The hollow core of the blocks provides excellent insulation, helping to keep buildings cooler in hot weather and warmer during winter. The insulation properties of hollow blocks contribute to energy efficiency and improved comfort inside buildings.
3. Compressive Strength
Hollow blocks are engineered to provide high compressive strength, making them ideal for load-bearing walls. The compressive strength of concrete hollow blocks is designed to meet the requirements of modern buildings and withstand various environmental conditions.
4. Eco-Friendly
Eco hollow blocks are an environmentally friendly option as they can be made using recycled materials and require less energy to produce compared to traditional bricks. Additionally, the hollow structure reduces the amount of material used, leading to lower environmental impact.
Disadvantages of Hollow Blocks
While hollow blocks offer many advantages, they do have some drawbacks:
1. Brittleness
Hollow blocks can be more brittle compared to solid blocks, especially if the compressive strength is not adequate. This can make them more prone to cracking under certain conditions.
2. Water Absorption
Certain types of hollow blocks may absorb moisture, which can lead to reduced durability in humid or wet environments. This can be mitigated by using high-quality concrete and applying protective coatings.
3. Higher Initial Cost
While hollow blocks offer long-term savings, the initial cost can be higher than traditional bricks, especially if high compressive strength is required for the project.
Compressive Strength of Hollow Blocks
The compressive strength of hollow blocks plays a critical role in determining their suitability for different construction applications. The standard compressive strength of hollow blocks is typically 5 N/mm² to 10 N/mm², but there are also high-strength variants available for more demanding projects.
A compressive strength of concrete hollow blocks lab report typically measures the blocks’ ability to withstand pressure and provides data on their durability. Builders use this information to determine the right block for specific building needs.
Uses of Hollow Blocks in Construction
Hollow concrete blocks are used in various applications, including:
- Walls: Hollow blocks are ideal for both internal and external walls due to their insulating properties.
- Partitioning: Lightweight hollow blocks are often used for partition walls in residential and commercial buildings.
- Foundations: Some construction projects use hollow blocks for foundation work, as they can offer better weight distribution than solid blocks.

Finding a Hollow Block Factory in Bangladesh
For those looking to purchase hollow blocks in bulk, finding a reliable hollow block factory in Bangladesh is crucial. The best factories offer high-quality products that meet international standards, ensuring the compressive strength of hollow blocks is consistent and reliable. Many manufacturers also provide research study about hollow blocks that helps consumers understand their material properties and advantages.
Conclusion
In conclusion, hollow blocks are an excellent choice for construction projects in Bangladesh due to their affordability, strength, and versatility. Whether you’re building a hollow block wall, partitioning rooms, or focusing on insulation, hollow blocks provide a durable solution. By understanding their price, size options, and properties like compressive strength, you can make informed decisions and choose the best product for your needs.
Always consult with suppliers and check hollow block quality standards to ensure you get the best value for your investment in Bangladesh’s thriving construction industry.
