Abstract
Prestressing steels are sensitive to stress-corrosion in the presence of ions like chloride, sulphide, nitrate, cyanide and ammonium. In general the concentration of these aggressive components is less in fly ash than in portland or portland blast furnace slag cement. Therefore, fly ash in concrete will not introduce stress-corrosion of prestressing steel due to the above-mentioned components. However, fly ash contains a few percent of carbon particles, which might induce galvanic stress-corrosion. Results obtained thus far from experimental research into the influence of fly ash in concrete on the stress-corrosion of prestressing steel show no significant adverse effect of the fly ash in this regard.
