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.
You can pour in cold weather, as long as certain precautions are taken. Concrete set time at 70 degrees is approximately 5 hours, at 50 degrees it is 10 hours, at 30 degrees itâs up to 20 hours (if the concrete doesnât freeze!).
