| Abstract: | In order to effectively assess the mechanical properties of concrete with freeze-thaw and seawater erosion,tests about basic mechanical properties of concrete after freeze-thaw and seawater erosion are conducted based on the large-scale static and dynamic stiffness servo test set.50,100,200 and 300 cycles of freeze-thaw cycling are made on normal concrete,and the artificial seawater is produced.The reasonable wet and dry accelerate system is selected.10,20,30,40,50 and 60 cycles of wet and dry cycling are m... |
