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.
Third the required cure time for concrete is a minimum 7 days to apply load to the foundation walls as well as foundation (footings) unless using a high early strength concrete. Final cure date is 28 days from placement date, which is considered the adequate duration of curing by the American Concrete Institute.
