Impact of high volume E.M.D. residue on the corrosion resistance and mechanical properties of construction materials in sulfate environment

Abstract This study examines the potential use of Electrolytic Manganese Dioxide (EMD) residue as a replacement cement (20%wt by weight) in construction materials to provide anticorrosion protection on reinforcing steel and improve strength cementitious under sulfate attack. To assess corrosion parameters, constructed building were immersed 5%wt salt (Na 2 SO 4 ), while concrete samples incorporating 20%wt EMD prepared subjected mechanical, porosity thermal tests. Moreover, SEM images obtained order examine microstructure extent damage caused ions. The results demonstrate that inclusion notable rise bars within mortars, well decrease mechanical materials. Overall, experimental outcomes suggest incorporation high volume (20%wt) leads degradation all measured properties.
