Abstract

Freeze-thaw damage and sulfate attack are two important factors that affect the durability of panel concrete. The damage of panel concrete with w/c ratio of 0.45, 0.42, 0.38 under the single freeze-thaw cycles, single sulfate attack and the alternation test in solutions of 5.0% Na2SO4 is studied, and analyzed the characteristics of mass loss and relative dynamic modulus. The results show that the w/c ratio have great influence on the panel concrete frost resistance and resistance to sulfate attack. The resistance of freeze-thaw and sulfate attack increased with the decreasing w/c ratio of panel concrete. Coupled deterioration of freeze-thaw cycle and sulfate attack is not a simple superposition effect, these two kinds of damage are promoting and influencing each other. The re-search methods and results can provide a reference for the durability of panel concrete.
