Corrosion of Low Calcium Fly Ash Geopolymer Concrete: A Preliminary Study

摘要：

A study of the durability of geopolymer concrete is a step forward in ensuring this materials technical viability. Geopolymer concrete from low calcium fly ash was reported to have a good resistance in aggressive environments, such as acid and sulfate. This research presents a preliminary study of the corrosion resistance of low calcium fly ash geopolymer concrete. The resistance of geopolymer concrete against damage caused by corrosion of steel reinforcement has been investigated using an accelerated impressed voltage setup in 4％ sodium chloride solution. The chloride resistance, water absorption and sorptivity of the concrete were also determined. An SEM investigation of geopolymer microstructure was also presented. The results of the test indicated that the geopolymer concrete has a good resistance to corrosion in a chloride solution environment.
