- Effective mortar application: Applying the appropriate mortar mix and ensuring proper adhesion between the blocks is crucial for a strong bond.
- Use of reinforcement: Adding steel bars or rebar within the hollow cores of CHB enhances the structural integrity and resistance against external forces.
Note: Understanding the advantages, types, recommended uses, and techniques for CHB laying and bonding is essential for achieving robust and durable masonry construction in the Philippines.
Advantages Of CHB: Durability, Strength, And Affordability
One of the major advantages of CHB is its durability. These blocks are designed to withstand various weather conditions, seismic activities, and other external forces. When properly installed, CHB can ensure the structural integrity of buildings over long periods. Moreover, CHB offers exceptional strength, making it suitable for load-bearing walls and other crucial parts of the structure.
In addition to durability and strength, CHB is also highly affordable. The cost-effectiveness of these blocks makes them a popular choice in the construction industry, especially in the Philippines. By utilizing CHB, construction projects can be completed within budget, without compromising quality.
- CHB provides durability and structural integrity.
- It can withstand various weather conditions and seismic activities.
- CHB is highly affordable and cost-effective.

Types Of CHB In The Philippines: CHB 6″ And CHB 4″
In the Philippines, the two most common types of CHB (Concrete Hollow Blocks) are CHB 6″ and CHB 4″. The numeric value indicates the width of the block in inches.
CHB 6″ is recommended for exterior walls and areas that require higher load-bearing capacities. It offers greater strength and durability, making it suitable for withstanding external forces and supporting heavy loads.
On the other hand, CHB 4″ is commonly used for interior walls and partitions. It is designed to handle lower loads and is sufficient for dividing spaces within a structure.
These variations in block size allow for flexibility in construction design. Architects and engineers can mix and match different block sizes to meet specific structural requirements. By doing so, they can optimize space utilization and ensure optimal structural stability.
In summary:
- CHB 6″ is recommended for exterior walls and areas requiring higher load-bearing capacities.
- CHB 4″ is commonly used for interior walls and partitions where lower loads are expected.
“These variations in block size allow for flexibility in construction design, as they can be mixed and matched to meet specific structural requirements.”
Recommended Use: CHB 6″ For Exterior Walls
For exterior walls, CHB 6″ is the preferred choice due to its higher load-bearing capacity. The larger size of CHB 6″ ensures better resistance against external forces and provides enhanced protection against elements such as wind and rain. Using CHB 6″ for exterior walls contributes to the overall strength, stability, and longevity of the structure.
It is important to consult with architects and engineers to determine the appropriate block size for different parts of the building. By following their recommendations, construction professionals can ensure that the finished structure meets safety standards and withstands the test of time.
- Consult with architects and engineers for appropriate block sizes
- CHB 6″ offers higher load-bearing capacity and better resistance against external forces
- Using CHB 6″ for exterior walls enhances protection against wind and rain.
CHB Laying And Bonding: Techniques For Wall Strength And Durability
Laying CHB (Concrete Hollow Blocks) involves several elements, including the CHB blocks themselves, mortar, and rebar. Structural bonding is a crucial step in achieving wall strength and durability. When laying CHB, it is important to carefully align the blocks, ensuring proper mortar coverage and embedding the rebar in specific locations to reinforce the structure.
Two important terms used in CHB bonding are headers and stretchers. Headers are CHB blocks placed perpendicular to the direction of the wall, while stretchers are blocks laid parallel to the wall. These distinct patterns contribute to the overall stability and strength of the structure.
It is recommended to source materials from the same supplier to ensure better compatibility between the CHB blocks, mortar, and reinforcing materials. Using different materials from various sources may lead to inconsistencies in texture, size, and strength, compromising the structural integrity of the building.
There are various bonding patterns available for CHB, but the most common is the Running Bond. This pattern involves aligning the blocks in a staggered formation, creating a strong and visually pleasing arrangement. The American Bond is a variation of the Running Bond, featuring headers placed at regular intervals, adding extra stability to the wall.
Other bonding patterns include Flemish Bond and English Bond, which both alternate headers and stretchers, creating visually appealing patterns. However, it is crucial to note that Stack Bond should not be used for load-bearing walls, as it lacks the necessary structural reinforcement.
To ensure safety, durability, and strength, it is essential to use high-quality CHB blocks, mortar, and rebar. Cutting corners by using subpar materials can compromise the overall quality of the building and put occupants at risk. By employing proper techniques, following recommended guidelines, and using quality materials, the full potential of CHB can be harnessed in masonry construction.
In conclusion, CHB, which stands for Concrete Hollow Blocks or Concrete Hollow Bricks, plays a vital role in masonry construction in the Philippines. With its durability, strength, and affordability, CHB offers numerous advantages for constructing buildings that can withstand the test of time. Understanding the different types of CHB, their recommended uses, and the techniques for CHB laying and bonding are essential for building professionals in order to ensure the structural integrity and longevity of construction projects.
