Fly Ash Concrete
Concrete, typically composed of gravel, sand, water, and Portland cement, is an extremely versatile building material. While significant environmental problems result from the manufacture of Portland cement, a waste product of coal-fired power plants can be substituted, significantly improving concrete's environmental characteristics.
Fly ash, a noncombusted by-product of coal-fired power plants, forms a compound similar to Portland cement when mixed with lime and water. Fly ash generally ends up in a landfill, however, when high volumes are used in concrete, it creates a stronger, more durable product and reduces concrete's environmental impact considerably.
Download this fact sheet from Build It Green to learn about the benefits of using high volume fly ash concrete over conventional concrete including:
- Less energy intensive manufacture
- Higher ultimate strength
- More durable
- Requires less water
- Uses a waste by-product
- Creates fewer global warming gases
- Potentially contributes to obtaining credits in LEED certification program
