✦ Synopsis

Measurements of physical properties and water leaching behaviour of cement blending variable amounts of pentachlorobenzene are described. The results indicate a slight decrease (48 to 38 MPa) in compressive strength when increasing amounts (0 to 13%) of pentachlorobenzene were blended in cement. The leach tests carried out at 50°C in distilled water indicate a very low concentration of pentachlorobenzene (about 900 ng in 400 mL) in the leachate. The results of previous investigations concerning immobilization of 1,3,5-trichlorobenzene have been compared with those of pentachiorobenzene. This indicate the feasibility of using Ordinary Portland Cement as a good confinement matrix for the immobilization of 1,3,5-trichiorobenzene, pentachlorobenzene and polychlorinated benzenes in general.
