Design and execution of repairing plan for defective concrete of Stands 2 and 4

Kavir Steel Complex is one of the largest steel production complexes in the country near Isfahan and Tehran, which has a production capacity of 900,000 tons of steel per year. Its production capacity will reach one million and five hundred thousand tons of steel per year by performing development plans in this complex.
Stands 2 and 4 of this complex have suffered from corrosion and cracking due to being exposed to acid vapors, so repairing and correcting these corrosions and taking measures to prevent corrosion in the future are the main characteristics of this project.

PROJECT DETAILS

PROJECT NAME	Design and execution of repairing plan for defective concrete of Stands 2 and 4
EMPLOYER	Kashan Kavir Steel Complex
LOCATION	Kashan
SERVICES	Concrete demolition, rebar planting, injection into concrete, repair and protection of concrete surface

PROJECT HIGHLIGHTS

Execution of the plan in 4 days on a 24-hour basis

Challenges

As is mentioned, stands 2 and 4 of Kavir Kashan Steel Complex have been affected by acid vapors since the start of operation. These vapors were able to cause concrete corrosion and due to the spread of this corrosion, the mentioned stands also suffered from shear cracking. Therefore, while repairing the concrete, it was necessary to think of measures so that the concrete would not corrode and crack in the future.

Solutions

In order to solve the mentioned challenges, first, the defective concrete was completely removed. Then injection was executed into concrete deep cracks. Finally, the connection between the old and new layers of concrete was established by using methods such as rebar planting and epoxy adhesives. Also, to protect the concrete surface, an anti-acid coating was applied on its surface to prevent the penetration of acid vapors into the concrete in the future.

Results

The implemented repairing plan has been able to have a good performance against acid vapors and environmental conditions during the years that have passed its life. In fact, these two stands have maintained their functionality without any cracking or sign of corrosion.
