Principles and Soil Mixing Examples of Portland Cement-Based Solidification/Stabilization Treatment

摘要

Solidification/stabilization (S/S) treatment is used to treat hazardous wastes for disposal and in the remediation/site restoration of contaminated land. S/S is also an increasingly popular technology for Brownfield (industrial property) redevelopment, since treated wastes can often be left on-site and to improve the soil for subsequent construction. This paper discusses the applicability of the technology to various wastes, basic cement chemistry relating to S/S, tests used to design treatability studies and to verify treatment, basics on implementation of the technology in the field, and examples of S/S use at brownfield sites, including a former wood preserving site, former manufactured gas plant sites, a former electric generating station, and a shopping mall development.
