Issue
Concrete damage due to chemical attack, harsh environment, and service of molten sulfur.
Cause
Water intrusion causes sulfurous acid that attacks the cementitious paste of concrete, causing a chemical attack and degradation of the structural elements below the ground storage pit along with embedded metal corrosion of the reinforcing steel that comprises structural integrity.
Why Béton
With past knowledge of these types of structures, Béton was consulted for an investigation, engineering, and construction of a new “structural liner” to be installed in the below ground molten sulfur storage structure. New reinforcing steel was installed per ACI 351 and a high sulfate resistant, shrinkage compensating, corrosion inhibitor cementitious repair product was selected due to past performance.
Repair Methodology
With feedback from Béton’s construction and suppliers, Béton:
- Installed new reinforcing steel
- Installed engineering formwork and bracing
- Installed 95 CY of a specialty repair material, new 12″ thick walls
- Removed forms and allowed client to reinstall all mechanical elements
