Using Fly Ash in Concrete

How Fly Ash Concrete Works. It's only the most common type of cement in use around the world, and the main ingredient in most types of concrete. Lime and silica make up the bulk of Portland cement, and it also includes aluminum and iron. Most types of Portland cement contain a mix of limestone, chalk, shells, and a variety of clay, shale and sand.

How Fly Ash Concrete Works

Fly ash is produced when coal is burned, and environmental laws in the United States require power companies to trap and properly dispose of it. Disposal presents a challenge because of the sheer amount of coal ash produced by coal-fired power plants, and also because the heavy metals in coal make fly ash a potentially dangerous substance.

Compaction of Fly

Jul 16, 2007To make a useful construction material out of fly ash, agents such as lime or cement are added to stabilize it (such as flowable fill). Fly ash contains the concentrated heavy metals from coal which can contaminate groundwater. Lime or cement lock the these contaminants in place and make the use of flowable fill environmentally acceptable.
