What is Concrete Cover?

Concrete cover is a design parameter used to ensure the longevity, strength and durability of a building structure. It is made of concrete reinforced with steel bars or mesh to increase the building's overall strength. It serves as a protection mechanism against elements like chemicals, moisture and other environmental factors. It helps to safeguard the structure from any potential corrosion and other damages that may endanger the building structure.

What Is The Nominal Cover As Per Indian Standards?

According to the Indian building code IS 456:2000, the required concrete cover is as follows:

• Slab = 20mm
• Column = 40mm
• Beam = 25mm
• Footing = 50mm

The Importance of Concrete Covers for Reinforcement

There are many reasons why concrete covers are important. Read more on the importance over here: 

• Protection from Corrosion

This is one of the primary importance of concrete covers. It helps prevent any corrosion by preventing the steel bars from being exposed to moisture and oxygen in the air. This helps to enhance the durability and strength of the building and ensure its long life.

• Fire Resistance

Concrete covers provide resistance against fire. Since concrete is more resistant to fire in comparison to steel, it acts as a cover for the steel, preventing heat from reaching inside the structure. This helps increase the safety of the building in case there is a fire accident.

• Durability

The concrete of the cover helps to protect the steel from environmental damage. This includes exposure to chemicals, any form of abrasion or high temperatures of heat. These factors can damage the steel over time, causing a building structure to fall.

• Bond Strength

The appropriate amount of concrete cover can help achieve the right bond strength between the steel and the concrete. This bold is important for the transferring stresses between the steel and the concrete which ensures the stability of the entire structure.

• Crack Prevention

By using concrete covers, you can prevent cracks from occurring in the concrete due to variations in temperature, shrinkage and other environmental factors. It is important for the long life and integrity of the building structure.

• Quality Control

The use of concrete cover requires meticulous techniques and practices. Starting from the placement of concrete to the consolidation techniques, it can impact the overall quality and structure of the building. Not using proper concrete cover may lead to unstable buildings and pose a risk to the safety of people in the future.

• Guidelines in Design Code

When constructing buildings, there is a minimum standard that must be met for the concrete cover requirements. Not adhering to these codes will lead to improper structures, unstable buildings and increased danger in the lives of people. Compliance with design codes and other important guidelines is important during the process.
