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.
Concrete will continue to set and settle for anywhere up to 20 years. In warm weather, a concrete slab can be walked upon the afternoon of a morning pour. A builder will typically allow 2-3 days before applying any loads, but will keep back propping in for a few weeks to prevent collapse. It is designed to reach it's designated strength 28 after pouring. i.e. 32MPa concrete should reach 32MPa 28 days after pouring.
