![]() ![]() ![]() 13,14 It can penetrate into concrete in diverse forms drawing on the chemical sources of SO 4 2− anions from the environment, which also promotes corrosion of steel rebar in concrete. 11,12 In this case, the Cl − anion can easily penetrate concrete structures through capillary adsorption, hydrostatic pressure, or diffusion, accelerating steel rebar corrosion ( eqn (1)). Penetration of Cl − anions to reinforced concrete is significantly detrimental, especially for structures near marine environments exposed to high concentrations of salts. 8 Corrosion is generally initiated by electrochemical flow of electrons and ions. Three major anions from different sources are particularly harmful: chloride (Cl −), sulfate (SO 4 2−), and carbonate (CO 3 2−) anions. 4–6 Nevertheless, corrosion of steel rebar can be readily initiated when passivity is compromised by damage 7 or when the bond between concrete and steel rebar is destroyed by anionic species. 2,3 In general, concrete structures present good durability to corrosion because the structure of concrete presents high alkalinity in the pores of the surrounding concrete, forming a protective, passive layer on the surface of the steel rebar. 1 However, it is always exposed to corrosion, leading to deterioration in concrete structures, which determines their durability and life span, particularly in natural environments. Introduction Building in concrete structures with steel rebar was a remarkable innovation in the construction industry because it adds strength to concrete, providing durability and allowing more specialized designs. The novel adsorption mechanisms of these CaFe-LDHs-induced crystals and corresponding corrosion protection properties are elucidated drawing on synergy of memory effects and chemical reactions. ![]() Furthermore, the steel rebar exposed to an aqueous solution containing the three anionic sources shows a fast corrosion rate (1876.56 × 10 −3 mm per year), which can be remarkably inhibited showing 98.83% of corrosion inhibition efficiency when it is surrounded by those CaFe-LDHs. The synthesized CaFe-LDHs with phase transfer show notable improvement of removal capacity ( Q max) toward Cl − and SO 4 2− over 3.4 times and over 5.69 times, respectably, then those of previous literatures. It is applied for the removal of Cl −, SO 4 2−, and CO 3 2− anions as well as corrosion inhibition on steel rebar in aqueous solutions. Here, we synthesize CaFe-layered double hydroxide (CaFe-LDHs) by a simple one-step co-precipitation technique and structural modulation by calcination process. Efficient removal of these deleterious anions at the early stage of penetration is crucial to enhance the lifespan and durability of concrete structures.
