Abstract
none10Research carried out in the scope of the IMPRESA project supported by POR-FESR 2014-2020 funds (Call 2018)Recently, within the field of new cementitious building materials development, there has been a grow-ing interest in the use of biochar, which represents the solid by-product resulting from biomass pyrol-ysis or gasification processes. The addition of biochar particles into concrete admixures can offer an eco-friendly carbon sequestration solution while possibly improving concrete mechanical properties. However, the role of biochar on durability of concrete and steel corrosion is still unexplored. Within this context, this work presents the first results in terms of corrosion potentials (Ecor) polarization resistance (Rp) measurements and electrochemical impedance spectroscopy (EIS) recording, of an extensive study on the influence of biochar as a concrete additive during wet and dry (w/d) exposures in saturated Ca(OH)2 solution, containing 0.1 N CaCl2.mixedFederica Zanotto, Alice Sirico, Francesca Vecchi, Andrea Balbo, Patrizia Bernardi, Beatrice Belletti, Alessio Malcevschi, Vincenzo Grassi, Sebastiano Merchiori, Cecilia MonticelliZanotto, Federica; Sirico, Alice; Vecchi, Francesca; Balbo, Andrea; Bernardi, Patrizia; Belletti, Beatrice; Malcevschi, Alessio; Grassi, Vincenzo; Merchiori, Sebastiano; Monticelli, Cecili
