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.
When it comes to protecting a concrete foundation you only have one chance to build a concrete foundation right the first time. Typical Spray-on-coatings may take from 12-72 hours or longer to fully cure. However, a concrete foundation may take up to 60 days before it reaches maximum strength. When a coating is applied to a concrete foundation it may seal in moisture, which could result in the concrete foundation taking longer than necessary to cure.
