Challenge details:

Manufacturing facilities located near the seashore experience severe structural degradation in both RCC (Reinforced Cement Concrete) and MS (Mild Steel) components due to high exposure of corrosive environment. Structures (10-15 Yrs old) are also exposed to a highly corrosive coastal environment and operate with a range of industrial chemicals, including sulfuric acid, hydrochloric acid, nitric acid, caustic soda, and other various solvents. Third-party inspections are conducted on such structures periodically which includes both destructive and non-destructive testing methods, such as carbonation tests, hammer tests, and core sampling. Actions are taken based on the findings of such inspections.

Possible outcomes of such inspections can be RCC degradation, corrosion in MS structures (pipelines) and support frameworks. Currently these structures are regularly maintained with epoxy coatings and protective painting. However, the combination of corrosive environment and chemical operations has made it difficult to ensure long-term durability. Despite active monitoring and maintenance, MS structures continue to degrade, posing operational and safety risks.

We are seeking for innovative, cost-effective, and sustainable solutions to protect from corrosion and extend the service life of both RCC and MS structures. The proposed solutions should aim to provide a minimum of 10 -15 years of protection under these challenging conditions.
