Have now managed to finish the concrete base for the shed. Due to mixing
by hand I done this over 2 days. (9x6 shed)
How long should I leave (concrete to cure) before attempting to re
assemble the shed, this should be interesting I just hope all my
measurements are correct.
Also, will rain affect the concrete after 24 hours as I want to start
clearing up all the rubbish including ploythene sheets as the other half
is complaining that the back garden resembles a builders yard.
Taken me 60 years to get a back garden that looked industrious and now
she complains :-)
It will still be "green" after a day or so, but should take light foot
traffic by then. If placing heavy loads like a car on it, then it needs
at least 7 days. So three to four days for a shed sounds ok. It will
achieve about 50 - 80% typically of its ultimate strength in a month
(reaching "full" strength can take years!).
Once its set enough to stop the cement being washed away, water won't
hurt it... (concrete will set when submerged)
Theoretically, concrete never completely hardens.
However it is usually taken that it has achieved 90% of strength in 21
How fast it cures depends on how hot it is..
You should be able to walk on it in 24 hours. Erect you shed in three or
Keep it wet down and ideally covered with plastic sheet for the next few
days. This adds to finished strength enormously.
Not really very clever doing a job like this in two lots.
Thanks all for the info.

As per a previous post I had no choice really, budget run out and heart
condition, although excercise is good its not wise for me to keep at it
until finished like the good old days.
