Material and its Properties
All concrete contains 30% fly ash, a by-product of coal-fired power plants. It also contains 20% slag, a waste product from metal smelting. These industrial by-products would otherwise be destined for a landfill. The use of locally extracted aggregates for the concrete mix is a major contributing factor in the quest for a LEED platinum rating.
