I visited the Green Concept Home last week to see the finished conrete pour for the slab foundation and it's really starting to take form.  I noticed that they used calcium chloride in the mix, and without speaking with owner David Huang, I'm assuming they used it to accelerate the setting time of the concrete.  Smart, because with the inclimate weather we're having, they want it to set quickly!

Next step, installation of S.I.P's (structural insulated panels).  I will be leading the second tour this Thursday at 1:00pm.  Go register at my homepage.
