Fly Ash is a by-product of burning coal in power plants. This and other coal-combustion products were originally treated as waste and disposed of in landfills. Now, power plants take the fly ash, captured from the exhaust of the boiler, and sell it to be used in products like concrete, brick, block, paving, and structural fills creating a more durable, smoother-flowing product.
The use of fly ash replaces up to 30% of carbon-dioxide (CO2) producing Portland cement in concrete.
U.S. power plants produce millions of tons of fly ash annually. According to the industry, about thirty percent of the fly ash produced in the United States is recycled into concrete mixtures.
The benefits of using fly ash concrete are:
- Diverts fly ash from landfills
- Reduces Carbon Dioxide (CO2) emissions
- Creates less permeable and more durable concrete
- Has less shrinkage than regular concrete
Old concrete slabs, walls and sidewalks can be recycled too. If you are tearing up concrete in your project, check locally for a concrete recycling business.
