Corrosion of Steel Reinforcements in Fly Ash- and Kaolin-based Geopolymer Con…

Abst ract: Corrosion behavior of steel bar in fly ash- and kaolin-based geopolymer concrete immersed in aggressive media of distilled water and ASTM seawater was compared to Portland cement concrete having similar mix design. An accelerated corrosion by applying 3 V potential on the steel bar was peiformed to obtain reasonable test results in a relatively short time. The potential and pH of the…
