Bio-based admixture with substances derived from bacteria for the durability of concrete

Résumé

The performance of a bio-based admixture was evaluated to function as corrosion-inhibitor for steel bars used in concrete as reinforcement. Electrochemical methods, such as linear polarization and impedance spectrometry, were used to check the influence of the bioadmixture towards steel corrosion in the presence of sulfates and chlorides in aqueous solutions, representing the composition of concrete pore solutions. The bioadmixture prepared from bacterial extracellular substances is shown to significantly improve the resistance of steel towards uniform and localized corrosion in simulated interstitial solutions.
