Given the concerns about the corrosion of low-carbon steel-reinforced concretes exposed to moisture, several prevention and repair methods have been explored in the literature and applied in construction. Among these solutions, corrosion inhibitors used both as preventive treatment (applied as additives to concrete) and as repair (applied to the surface of hardened concrete), have gained wide recognition. Thus, this study focuses on the collection and analysis of data from the literature on the effects of corrosion inhibitors on corrosion potential (Ecorr) and corrosion rate (icorr) in cementitious materials exposed to accelerated carbonation (CO₂) and/or chloride ion (Cl⁻) attack. Since prevention should be a priority, data were collected on the effects of inhibitors used as additives on fresh and hardened properties of concrete. The results indicated that most of the data with a low corrosion probability (Ecorr ≥ −200 mV) and within the passivation zone (icorr ≤ 0.1 µA/cm2) were related to concretes with cement content of 300 kg/m3 or more. However, much less data is available on their performance at low cement content and focused predominantly on sodium nitrite-based corrosion inhibitors in environments exposed to Cl⁻ attack, although the results were generally unsatisfactory. Regarding the effects of corrosion inhibitors on fresh and hardened properties, few studies have evaluated them alongside their efficiency of electrochemical responses in reinforced cementitious materials. This highlights the significant need for advances in the durability of low-carbon concretes.
