Like most concrete products, CDF provide many green benefits. See associated sustainability solutions and technical briefs (right) for more detail.
Local. Materials are usually extracted and manufactured locally. May contribute to LEED Credit M 5.
Recycled content. Fly ash, slag cement, or silica fume can substitute partially for cement, and recycled aggregate may be used. Recycled content can contribute to LEED Credit M 4.
Durable and low maintenance. CDF provides a more effective fill in many circumstances.
Reduces Site Disturbance. Because CDF flows into voids it doesn't require as extensive excavation. May contribute to LEED Credit SS 5.
