Why Does Your Concrete Crack Quickly? Check the Quality of the Reinforced Concrete Used!

Concrete cracking is a common problem in construction that can cause structural damage and high repair costs. One of the main factors causing concrete to crack is the quality of the rebar used. If the rebar is not up to standard or is of low quality, the durability of the structure can decrease.

Here are some of the main causes of concrete cracking quickly related to rebar.

1. Rebar Does Not Meet SNI Standards

Rebar that does not meet the Indonesian National Standard (SNI) tends to have lower tensile strength. This can reduce the concrete's bearing capacity against loads and cause cracks to appear more quickly.

Solution:

• Use rebar that is SNI certified to ensure its quality and strength.
• Make sure to buy from a trusted distributor to get an original product with the appropriate specifications.

2. The Size and Type of Rebar Does Not Match Needs

Each project has different rebar specifications, depending on the load and its function. If the diameter of the rebar used is too small or does not match the structural design, the concrete is more susceptible to cracking.

Solution:

• Use plain or threaded rebar with a size that matches the project specifications.
• Consult a structural expert before purchasing rebar to ensure the right choice.

3. Poor or Fake Rebar Quality

Fake or low-quality rebar often has inappropriate material content, so its strength is not optimal. Fake rebar can also have a smaller diameter than stated, reducing its bearing capacity.

Solution:

• Check the weight and diameter of the rebar before use.
• Perform a tensile test to ensure the strength of the rebar meets the required standards.

4. Incorrect Rebar Installation Process

Errors in installing rebar, such as inappropriate spacing or weak connections, can cause the concrete to lose strength and crack more quickly.

Solution:

• Make sure the rebar installation follows the correct structural calculations.
• Use reinforcement that matches the pattern and spacing recommended in the building design.

Concrete that cracks quickly can be caused by various factors, one of which is the quality of the rebar used. To avoid this problem, make sure to choose quality rebar that meets SNI standards, pay attention to the right size, and ensure that the installation is carried out correctly.
