ᐅ Question about concrete

Hello everyone,

I have a general question:

Why does concrete need to cure over the winter? Why can’t it cure in spring or summer? It’s less "damp" and warmer then, so wouldn’t it "dry" better?

Hello,

This is the first time I’ve heard that 😱
Where did you get this information from?

I am not a construction expert, but everyday observations should be enough to explain this.
Often, the humidity is lower in winter than in summer, especially when it is very cold.
On a clear winter day, laundry dries particularly well.
Moisture from snow or rain, on the other hand, does not enter the house.

When it’s warm, you experience the phenomenon that moisture settles or condenses on cold surfaces.
Since concrete is cold, it actually attracts moisture.

We currently live in a valley by a stream. Because the house is generally cold inside, we especially struggle with moisture during the warmer months. Depending on the weather, the stairwell looks as if someone poured a bucket of water inside when the front door is left open for a long time in summer.

I’ve heard that before, too. They used to say the shell of the building should stand through one winter. But with today's construction methods, that shouldn’t be necessary anymore.

I've never heard such nonsense about concrete before.
I'm too lazy to go into detail now, but basically, there are definitely two things that concrete really doesn't like: frost and intense heat / sunlight.

In our average climate, it works well in spring and summer! If it gets really hot, simply cover the concrete with a tarp to keep it moist and allow enough time for it to set.
