How long does it take for the strength of 325 grade concrete to rise in rainy weather around 6 degrees?

Concrete pouring is not allowed when the average temperature is 5 degrees. You just do it at the critical point, which is very risky.

It's hard to say how long the intensity will come up. The weather will get warmer soon.

If it keeps 6 degrees and it rains, it will take half a month to get there. If the intensity is 28 days, according to the accumulated temperature of 600 degrees 100 days!

If it's freezing in recent days, there is a danger of scrapping if you don't take warm measures!
