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.
Also, the concrete will need to be reinforced so that it has a minimum strength of 2500 psi at 28 days. Yes, this is the standard curing time for a foundation or slab. Some acceleration agents can be added to speed things up, however. Extra reinforcement should be in the form of re-bar with wire or fiber mesh.
