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.
Just my opinion, but I think it's insane to do a 17 yard pour if there's better than 50 percent chance of rain in the next 12 hours. If the rain comes too soon and spoils your concrete, YOU are the one who will be listening to your daughter complaining about it for the next few years. The contractor will be long gone.
