Chloride induced corrosion in different fly ash based geopolymer concretes

This study investigates the corrosion of reinforcement in geopolymer concrete manufactured from three different low calcium fly ashes from Australian power plants. The long term corrosion condition of embedded rebar in fly ash geopolymer concretes containing cast in chlorides (0–5%) subjected to wet-dry cycles, together with specimens exposed to ponding in 3% NaCl were examined. Half-cell potential and linear polarisation resistance techniques...
