Full TextAbstract
In this research, the effect of marble and granite waste dust (MGWD) as partial cement replacement (up to 20%) on the mechanical and corrosion behaviour of concrete specimens was investigated. Water cured specimens were kept in a 3.5% by weight of NaCl solution for 92 days. Uniaxial compression and water absorption tests, open circuit potential (OCP), electrochemical impedance spectroscopy (EIS) and Scanning Electron Microscopy (SEM) analysis were conducted. The compressive strength test results showed insignificant negative effect from using MGWD. OCP and EIS measurements revealed that specimens with 20% cement replacement have higher potentials and corrosion resistance than all the others.
