How is cement-based solidification/stabilization done?
Cement-based S/S is done by mixing portland cement into waste or contaminated media such as soil, sludge, or sediment. Cement can be mixed into waste as it is generated by industry to make the waste safe for land disposal. During cleanup of contaminated land, cement can be mixed into contaminated soil, sludge, or sediment while the contaminated medium remains in place, or in situ. Or the cement can be mixed into the contaminated media after it has been excavated (ex-situ mixing).
