As I talk to people about the Show House for the 2007 Michigan Energy Fair and all the Green Building products in it people seem intreged by the use of Fly Ash in the concrete that is used in all the footings, ICF walls and the Lite-Deck floors. People ask what is it and why we would use it. So I desided to explain it here in my Blog. Fly ash is produced by burning coal at electric power plants fly ash might be destined for disposal in a landfill. But when added to concrete, fly ash makes concrete easier to work, stronger and more durable. Fly ash also enhances the enviromental performace of concrete. Mining and manufacturing of natural raw materials can be reduced along with decreasing greenhouse gas emissions. In fact, using a ton of fly ash can save almost a ton of CO2 emissions from being introduced into the atmosphere. Inaddition to concrete, fly ash is used in mortors, stuccos, paints, artificial stone, carpets, ceiling tiles, soil cement, pervious concrete and a variety of other building materials. Adam from Hybrid Homes (TM) used some great sub-contractors on the show house. Team Elmer's supplied, delivered and pumped the concrete with a 40% fly ash mix and R-Value Concrete Structures poured all the flat work and ICF walls and the Lite-Deck.
