Abstract:To evaluate water treatment residue (WTR) as a soil substitute material, its physical properties were investigated and compared with decomposed granite soil (DGS). For comparison purposes, relative gas diffusivity (D ⁄ D 0 ), saturated hydraulic conductivity (K s ), water retention curve, porosity and readily available water were measured for both the WTR and the DGS. The measured D ⁄ D 0 , K s , water retention ability and porosity were higher for the WTR than for the DGS. These differences may be attributabl… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
