“…The objective of the present investigation was evaluating through electrochemical techniques, the Eco-friendly Concrete based on the system CPC-SCBA-SF as a protector against sulfate corrosion of reinforcing steel AISI 1018, as a sustainable response due to evaluating the Eco-friendly concretes, promoting the use of Agro-industrial wastes and industries in order to substitute Portland concrete in the fabrication of concretes, which is going to allow a decrease in the use of cement and will be reflected on less emitions of CO2 by the cement industry, responsible of the 6 to 8% of the total CO2 emitions at global level [42]- [45].…”

In the present investigation, the protector against sulfate corrosion of reinforcing steel AISI 1018, which provides the Eco-friendly Concrete system CPC-SCBA-SF, was evaluated. This system was made with CPC-SCBA-SF cementitious materials, in percentages of 90-5-5 and 80-10-10 respectively, with exposure of the concrete specimens to a 3.5% MgSO4 solution, an experimental arrangement that simulates the foundations of Civil Works such as bridges, buildings, pavements, etc.; in soils contaminated with sulfates. The design of the concrete mixtures was in accordance with the ACI 211.1 method. The behavior of the corrosion potential Ecorr and the corrosion rate (icorr) of the AISI 1018 steel embedded in Conventional Concrete (CC) and in the EC were evaluated during a period of 180 days of exposure to an aggressive environment. The Ecorr values indicate between a 10% risk of corrosion and uncertainty, according to the ASTM C-876-15 standard, but the icorr indicates a negligible level of corrosion but with a tendency towards the activation of the system, with the eco-friendly concrete EC-20 having the best performance.

“…Unlike corrective or secondary actions, such as the use of corrosion inhibitors, galvanized steel, austenitic stainless steels, epoxy coating of the rods, electrochemical removal of chlorides, the production of more durable concrete based on industrial or agro-industrial residues [35]- [41], also pozzolanic materials when used in the construction industry have a beneficial environmental impact because the manufacturing process of Portland Cement is responsible for emitting 6 and 8% of CO2 in the world [42]- [45].…”

The electrochemical behavior of the corrosion resistance of AISI 304 embedded in concrete manufactured as indicated by the ACI 211.1 method was evaluated. The specimens were exposed for more than 150 days to highly aggressive marine-sulfated environment, solution with a concentration of 5% NaCl and 5% Na2SO4. The electrochemical technique of Resistance to Linear Polarization (Rp) was used for to determine the corrosion rate (Icorr) and monitoring of corrosion potential (Ecorr). The Ecorr and Icorr results indicate a high level of corrosion for AISI 1018 steel, on the contrary, the electrochemical behaviour of AISI 304 steel according to the values of Ecorr and Icorr, indicate a corrosion resistance of up to 10 times higher when exposed to an environment with a high concentration of chlorides and sulfates.

“…There have been many uses of industrial waste, fly ash (FA), and agricultural residues such as rice husk ash (RHA), and sugarcane bagasse ash (SBA) as a substitute for cement in concrete research [13]- [20]. This material aims to replace the depletion of natural resources and reduce CO2 emissions in the air from cement manufacture, which will help save the environment.…”
