Footings

It is hard to believe that on Monday morning we still had a house and by Friday afternoon the footings for the new house had been poured. 

Footings

We ordered a mix with 40% fly ash added to the concrete.  Fly ash is a waste product from coal-fired power plants and replaces portland cement, which has very high embodied energy because a large amount of carbon dioxide is generated in the production of cement.  This should lower the carbon footprint of the house and results in a stronger concrete.  The only drawback is that it sets slower, but there were no complaints from the guys with the trowels.
