The pH value of the hardened portland cement and concrete ranges from over 12.5 to values as high as 13.5, due to the presence of alkalis in cement. Partial replacement of portland cement with supplementary cementing materials such as coal fly ash, b

Solidification/stabilization (S/S) is often used to treat waste or to remediate contaminated sites. Many people feel S/S is just a process to consolidate waste into a solid product for disposal using cementing materials. This article describes design

Stabilization/solidification (S/S) is one of the most widely used techniques for the treatment and ultimate disposal of both radioactive and chemically hazardous wastes. But does not have regulatory approval for treating organics. Application with vo

A backfilled trench containing low-level radioactive waste was grouted with a particulate grout. The accessible void volume of the waste zone was estimated to be 20% or 28 m 3 , but 30.6 m 3 of grout was injected into thetrench. Part of the grout for

Mixed low-level radioactive and chemically hazardous process treatment wastes from the Portsmouth Gaseous Diffusion Plant are stabilized by solidification in cement-based grouts. Conventional portland cement and fly-ash grouts have been shown to be e
