the making of: concrete rings by 22 design studio


another batch of the 'concrete rings' designed by 22 design studio are for sale on the designboom shop.
22 design studio also sent us a few behind the scene snapshots of how their rings are made.


the cement and water are precisely mixd together


the metal ring part is place in the mould before the cement is added


the cement is inserted and tapped to remove air pockets


the cement is left to set for 2 days


then the ring is sanded clean and the metal is polished


the ring is then kept wet for 20 days

You can probably stain the concrete and polish it with a dremel.

Why is the ring kept wet for 20 days?
I would think the concrete would have to cure in open air.
Chris   03.25.08
You can also get colored powder to put color in the rings (they use it for coloring walkways...)

I also question the 20 day wait...it takes that much time to cure a 6 inch thick slab, so i would expect these to fully cure in less than 48 hours. Maybe it shrinks too much if it cures quickly (hence the water) and pops off the metal?
nathan   03.25.08
If it's just cement without aggregate, how is it concrete? I don't really think the metal ring counts as aggregate.

Perhaps 20 days is a bit long, but cement cures by a water-consuming chemical process. Having it cure while dry would lead to a weaker ring.

Tim, it's better to leave it uncolored, I think. Since the whole intent behind a cement ring is to aethesticise something that is normally industrial & not commonly thought of as pretty.

I would actually prefer a lighter concrete, or varying shades to match different skin tones. Cool grays and warm grays?
Mimi   03.26.08
The aggregate is probably powdered stone, and there are probably some other additives to improve cohesion at such a small size. The cure time for concrete is not necessarily related to the thickness of the piece, but rather the time it takes for the cement to fully bond with the surrounding aggregate and other cement.
