Cement is primarily used to produce concrete, the world’s most versatile and durable construction material. Some other applications for cement, however, are now growing in importance.
One of these is solidification/stabilization (S/S) – a widely used technique for the management and disposal of a broad range of contaminated materials and wastes, including radioactive wastes. Cement is mixed into the contaminated substance, immobilizing the contaminants and preventing them from migrating to plants, animals or humans. The process is most often used to reclaim polluted industrial sites for redevelopment or recreational use.
Engineered soils are another important application. Cement is mixed in to stabilize substandard soils as a base for buildings, roadways, airport runways, parking lots and other uses.
