Roof Slab for underground structure
Roof Slab for underground structure
(OP)
How soon can the formwork for the roof of an underground vault be removed and how soon can loading be allowed on top of it? This structure is an underground vault with dimenstion of 12'x12'x12' with thickness of 10" for all elements w/ 35MPa concrete.
Thanks
Thanks

In any case, it's unlikely you would have to wait a month, even with normal concrete.

And if you are putting in soil and compacting it, I assume the loading is going to be close to the full design load from the compacting process!

When full strength is reached (as determined from samples) remove temporary propping within.
