busy pouring our foundation. In talking with our EarthCraft builder, we learned that he is using fly ash concrete, a form of concrete which replaces some of the cement in the mixture with fly ash, the fine powdery residue from coal combustion. This produces a concrete that is stronger, more durable and easier to work with and diverts that fly ash generated by our coal-fired power plants from ending up in our landfills. Fly ash containing concrete mixes can receive LEED credit under the guidelines established by US Green Building Council. In the vein of there being nothing new under the sun, a form of volcanic fly ash concrete was used by the Romans in building the Coliseum and the first domestic use of fly ash concrete was in 1929 in the construction of the Hoover Dam.Wednesday, April 7, 2010
