Corrosion of steel reinforcement in geopolymer mortars - leaching and carbonation processes investigated by galvanostatic pulse and potential measurements
- Potential to be used as binders for concrete with beneficial engineering properties and reduced manufacturing CO2 emissions. Knowledge of the durability of steel in these concretes and related properties of alkali-activated materials is a prerequisite for their application as building materials, if they are to be used for steel reinforced elements. However, to date only limited data exists on this topic. The present contribution focuses on durability-related transport properties of geopolymer-based mortars (as model systems for concrete). We report results of a polarization resistance data and corrosion potential vs. time curves for carbon steel bars embedded in a fly ash-based geopolymer mortar and a CEM I-based mortar (as reference) leached continuously over a period of 365 days.
