How long does it take for salt to damage concrete?

All concrete is not created equal. The types of concrete that are most susceptible to spalling damage is freshly poured concrete and low strength concrete. Newly poured concrete, which is still holding a high water content already, usually needs around 30 days to “harden off” before rock salts can be used.

What is the safest salt for concrete?
