The recycled aggregate concrete(RAC) were respectively prepared with 0%,30%,50% of recycled aggregate made from C25 grade waste concrete,to research the effect of the recycled aggregate replacement ratio and the load on the corrosion resistance.Then the dry-wet test with the aggressive medium of artificial seawater under the effect of bending stress by 0,10,20,30,40 and 50 cycles were carried out on the RAC specimens to observe the influence of artificial seawater corrosion on the RAC internal damage.The results show that the bending stress has accelerated deterioration velocity of the material performance of RAC in environment of artificial seawater.Furthermore,the corrosion damage of RAC in artificial seawater decreases with the increase of recycled aggregate replacement ratio in the same bending stress coefficient,and the corrosion damage of RAC in artificial seawater increases with the increase of bending stress coefficient in the same recycled aggregate replacement ratio.
