If Concrete Cracks, Is It the Iron's Fault or the Worker's Fault?

Cracks in concrete are a common problem often encountered in construction projects. However, the cause of the cracks is not always clear, whether due to poor material quality or due to errors in installation. Then, if the concrete cracks, does it mean that the iron is the problem, or maybe the worker's error in the casting process? Let's discuss further.

1. Iron Quality That Does Not Meet Standards
The iron used in reinforced concrete construction has a very important role. If the iron used does not meet quality standards, such as iron that is easily corroded or does not meet the required specifications, then the binding power between the concrete and the iron can be disrupted. This can trigger cracks in the concrete.

Common causes:

• Use of threaded or plain concrete iron that does not meet the needs of the structure.
• Iron with less guaranteed SNI quality.

However, although the quality of the iron affects the strength of the concrete, cracks in the concrete are not only influenced by the iron.

2. Errors in the Casting Process
Errors in the casting process are one of the main causes of cracks in concrete. If the builder does not pay attention to the correct casting techniques, such as inadequate compaction, disproportionate mixing of materials, or drying too quickly, the concrete can crack.

Common causes:

• Uneven mixing of the mixture.
• Insufficient compaction (concrete is not perfectly solid).
• Poor curing process (lack of moisture in the concrete that is drying).

If the casting is done incorrectly, the concrete structure becomes more susceptible to cracking, even though the materials used are in accordance with standards.

3. Improper Iron Thickness and Distribution
In addition, errors in distributing iron or installing iron that does not comply with structural calculations can cause cracks. Concrete structures require proper planning in terms of concrete thickness and iron position to be able to withstand the given load. If it is not balanced, cracks can appear, even though the quality of the iron is good.

Common causes:

• Iron that is installed too rarely in certain areas.
• Insufficient concrete thickness to withstand the load acting on the structure.

4. Environmental Temperature and Humidity
Temperature and humidity also affect the concrete hardening process. Concrete that dries too quickly due to temperatures that are too high or not humid enough can cause cracks. This is more related to environmental conditions during the casting process, which are sometimes beyond the control of the craftsman.

Common causes:

• Weather that is too hot causes the concrete to harden quickly.
• Lack of maintenance on the concrete during the curing process.

5. Causes Involving Both Factors
It is not impossible for cracks to occur due to a combination of errors in the material and the craftsman. For example, even though the iron used is of good quality, errors in the casting process or maintenance can make the concrete less than optimal in supporting the load.

Conclusion: Wrong Iron or Wrong Craftsman?
In many cases, both can contribute to cracks in concrete. Although the quality of the iron is important, errors in casting and installation techniques can also be major factors. Therefore, it is important to choose the right material and ensure that the craftsman or construction worker is trained and follows the correct procedures.
