Sintering is part of the firing process used in the manufacture of pottery and other ceramic objects. 1  These objects are made from substances such as glass, alumina, zirconia, silica, magnesia, lime, beryllium oxide, and ferric oxide.
for our foundation, the footings were poured one day and the walls poured the next day. I think that is pretty standard. It is true that concrete takes 28 days to fully cure. 1 Like Bookmark January 20, 2010 at 12:44PM.
I would wait at least 30 days for it to set. Waiting 24 hours is definitely not long enough. The concrete needs at least 72 hours to cure to a point where it can be walked on and at least 30 days to completely cure, depending on the thickness of the concrete that you put down.am Gunner gave the correct answer. 24 hours is long enough. Concrete that is poured for a home will be cured enough to build on.
