DURABILITY OF CONCRETE INCORPORATING LARGE VOLUMES OF LOW-QUALITY FLY ASH
The carbonation, corrosion of steel reinforcement in concrete and corrosion resistance of concrete, incorporating large volumes of low-quality fly ash (LVLQFA), were studied in this paper. The effect of concentration of carbon dioxide used in the experiment on estimating the carbonation resistance of LVLQFA concrete was also investigated. Test results show that the LVLQFA concrete with an activator has good carbonation and corrosion resistances of steel reinforcement. The corrosion resistance of LVLQFA concrete is better than that of the control concrete. The concentration of carbon dioxide used in the experiment has considerable effect on estimating the carbonation resistance of LVLQFA concrete.
