Co-processing of hazardous wastes in cement kilns have for decades been thought to cause increased emissions of PCDD/PCDFs--a perception that has been evaluated in this study. Hundreds of PCDD/PCDF measurements conducted by the cement industry and others in the last few years, on emissions and solid materials, as well as recent test burns with hazardous wastes in developing countries do not sup...

Cement stabilization improves physical and mechanical properties of geotechnical materials. However, numerous combinations materials cement hinder to establish a pattern behavior cement-stabilized Thus, this study aims evaluate the soil-aggregate-cement mixtures (SAC) using high early-strength (HE), contribute dosage aspects ascertain their recommendation as base and/or subbase layers in heavy ...

This paper presents the findings of a study on solidification/stabilization (S/S) of lead-contaminated soil using ordinary Portland cement (OPC) and rice husk ash (RHA). The effects of varying lead concentrations (in the form of nitrates) in soil samples on the physical properties of their stabilized forms, namely unconfined compressive strength (UCS), setting times of early mixtures and change...
