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.
After it's poured, concrete will dry to the the touch after six hours. As long as the concrete has been allowed to dry on an even plane and there's no grade or slope to the driveway, this time will hold true. If the size or slant of the terrain is irregular, allow more time just to be safe. Allow eight hours to two days before walking on the newly poured concrete.
