Tips for Choosing Practical Columns That Are Sturdy and Crack-Proof

In the construction world, practical columns play a crucial role in reinforcing walls and maintaining structural stability, especially in 1-2 story houses.
Although often considered additional elements, practical columns actually function to resist lateral forces (pushing from the side) to prevent walls from cracking or collapsing.
Therefore, choosing sturdy, high-quality practical columns is crucial to ensuring the safety and durability of your building.

What is a Practical Column?
A practical column is a vertical structural element typically installed between brickwork or lightweight blocks (lightweight bricks).
Its function is to bind and strengthen walls, especially in areas with numerous openings such as windows or doors.
These columns are made of reinforcing steel and cast concrete with standard dimensions ranging from 10x10 cm to 15x15 cm, depending on the structural requirements.

Tips for Choosing Sturdy and Crack-Resistant Practical Columns
1. Use Quality Reinforcing Steel
Choose reinforcing steel (rebar) that meets SNI (Indonesian National Standard) standards to ensure its ability to withstand loads effectively.

The common steel size used for practical columns is 8 mm to 10 mm, depending on the height and function of the building.
Ensure the iron surface is rust-free to ensure optimal adhesion to the concrete.

2. Use a Concrete Mix with the Right Composition
The strength of practical columns is highly dependent on the quality of the concrete used.
Use a mix ratio of 1 part cement: 2 parts sand: 3 parts gravel for a dense and strong result.
Also, ensure the concrete is mixed evenly to avoid air cavities that could lead to future cracks.

3. Pay Attention to Column Spacing
Ideally, practical columns should be installed every 3 meters or at every corner and wall intersection.
If the columns are too far apart, the wall can experience excessive pressure and risk vertical cracks.
Proper spacing helps distribute the load evenly throughout the building structure.

4. Ensure a Neat and Solid Casting Process
Mistakes in casting often result in columns that are loose and prone to cracking.
Use strong formwork and ensure the concrete is poured slowly while vibrating to avoid leaving air cavities within the columns.

5. Use Precast Practical Columns for Speed
If you want a faster construction process, you can choose precast, or ready-to-use, practical columns.
This type of column is manufactured in a factory with strict quality control standards, resulting in more precise and sturdy results.
However, make sure you buy from a trusted supplier to guarantee quality.

Conclusion
Choosing the right practical column isn't just about shape and size, but also the quality of the materials and installation process.
By paying attention to the reinforcing steel, concrete quality, column spacing, and casting techniques, you can achieve columns that are sturdy, durable, and resistant to cracking.
