RISLong-Term Leaching Behavior of Chromite Ore Processing Residue as Backfill Material and the Propagation of Chromium in the Surrounding Soil
Publisher: ASCE
Abstract: Leaching characteristics of chromium ore processing residue (COPR) for the long term (simulating a 20-year leaching scenario) were investigated using laboratory flow-through column testing with synthetic rainwater and ...
Hydraulic Conductivity of Bentonite–Polymer Composite Geosynthetic Clay Liners Permeated with Coal Combustion Product Leachates
Publisher: American Society of Civil Engineers
Abstract: Experiments were conducted to evaluate the hydraulic conductivity of geosynthetic clay liners (GCLs) containing bentonite–polymer composites (BPCs) permeated with coal combustion product (CCP) leachates. Eight synthetic ...
Characterization of Recycled Concrete Aggregate after Eight Years of Field Deployment
Publisher: American Society of Civil Engineers
Abstract: Recycled concrete aggregate (RCA) is a high-quality substitute for virgin aggregate as base or subgrade material in pavement construction. However, heavy metal leaching and/or production of high pH leachate are environmental ...
