Concrete screed drying time


What is the minimum drying time for 150mm thick of concrete screed & how soon can we lay carpet. Have been told its 1mm per day which would mean 150 days! Can this be speeded up?

That time is probably close to right for it to "fully" cure. I wouldn't think you would have a problem putting the carpet down before that though. Speeding up concrete can be done but not always wise (can cause cracking and loss of strength) but keeping the room warm to hot and humidity low will help speed it up some. I saw carpet go in at a small office complex near me about 1 month after a concrete floor was poured. I have seen tile go on screeds in less then a week.

To the OP....you have basically a 6" slab.

Your issue is not strength.....but moisture. After 7 days, you are at about 75% of strength. After 30 days....about 90%. But moisture is a different issue.

The big factor in this is was a vapor barrier put down? If not, then expect to get moister weeping up for many years. If the vapor barrier was put down....you should be good to go after about 2-3 weeks (sorry, no conversion from imperial to metric for time)

Even fully cure concrete will weep moisture. That is why basements typically have sump pumps.

Concrete cures better when kept wet for about 10 days. Hosing it down once a day (maybe 3 times a day if in the sun and not temporarily covered) is suggested.

After that, give it time to dry out.

To expand on that....keeping it wet reduces the chances of cracks. If the top layer dries too quick, it shrinks faster than the under layer and causes cracks. So, keeping it wet (or covered) reduces the chances of cracks.

In reality....it does not really change the curing strenght/time of the concrete.
