Embodiment
[0024] The present invention takes recycled concrete as an example, and the specific mix ratio is shown in the following table.
[0025]
[0026] Stir according to the above mixing ratio, and form a 40mm×40mm×160mm concrete specimen. After forming, it will be cured with the mold for 24 hours. After the mold is removed, it will be placed in a standard curing room (temperature 20±1°C, RH above 95%) for 56 days; After drying in a drying oven at 60°C for 48 hours, the first round of XCT scanning was performed, recorded as the information that the corrosion age was 0 days, and placed in a dry-wet cycle simulation test chamber. The dry-wet cycle system is set as follows: the cycle is 3 days, soaked in sulfate solution for 21 hours, air-dried at room temperature for 3 hours, dried at 60°C for 45 hours, cooled at room temperature for 3 hours, and the dry-wet cycle is one cycle. After the number of dry and wet cycles was 10, 30, 60 and 100, the specimens were taken out, and the sec...
