Abstract:
This study addressed carbonation in reinforced concrete structures, highlighting its
recurrence and impact on durability and strength. Flaws in the design of the structure
were identified, highlighting the importance of pre and post-design. Based on NBR
8681:2003, we explored the consequences of carbonation on the useful life of
structures. The general objective was to analyze the impacts of carbonation,
including causes, effects and preventive and remedial measures. Specific objectives
included observing the formation, investigating causes and prevention methods. The relevance of carbonation to reinforcement corrosion, the risk of cracking and repair
costs was highlighted. The carbonation process, influenced by humidity, temperature
and concrete composition, was detailed. Identification involved methods such as the
phenolphthalein test. Preventive measures included coatings, corrosion-inhibiting
additives and surface treatments. Recovery strategies after detection were outlined.
The importance of proper design, skilled labor and care when curing concrete was
stressed. The relationship between hydration and durability was explored, with
emphasis on controlling the heat of hydration. The conclusion emphasized the
importance of personal strategies to mitigate the effects of carbonation in reinforced
concrete structures.
