Effect of Carbonation on the Sulfate Attack of Concrete Materials

Abstract:

In this paper, experiments have been carried out to determine the effect of carbonation on the resistance of sulfate attack of concrete materials. The accelerated carbonate testing was used to prepare the carbonated specimens, and wetting-drying cycles were used to evaluate the resistance of sulfate attack. Results show that longer carbonate time leads to greater depth of carbonation, and fly ash may accelerate the carbonation of concrete materials. The loss of flexural strength was greater than that of compressive strength under the condition of sulfate attack. Carbonation is detrimental to the resistance of sulfate attack.
