摘要：
The effects of mixed erosion and freeze-thaw cycles on the mechanical properties of concrete were experimentally studied. A mixed solution of NaCl and Na2SO4 was used as erosion medium. Results show that under alternative actions of and mixed erosion, by increasing the number of freeze-thaw cycles, compressive strength and elastic modulus of concrete decrease, whereas deformation capacity increase. The degradation of concrete material properties accelerates with the increase of water-cement ratio.
