Modelling compacted soils

open access: yes, 2011
Mechanical and hydraulic compacted soil properties for a given soil mineralogy are essentially controlled by the attained dry density, water content and microstructure. Basic compaction conditions (wet or dry of optimum, higher or lower energy of compaction) result in changes in microstructure.

Research on the Detoxification of Municipal Solid Waste Incineration Fly Ash: Organic Acid Washing Pretreatment Coupled With Cement/DDTC Stabilization

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

Soil compaction loosener

open access: yes, 2018
A relationship between tire sinkage depth and compaction depth was developed from the literature describing previous research. Laboratory and field experiments were conducted to verify that relationship. For the laboratory experiment a universal testing machine was used with the aid of dimensional analysis and modeling theory to physically simulate ...

Adsorption Characteristics and Mechanisms of Dibutyl Phthalate on Nanomaterials

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Dibutyl phthalate (DBP) is a widely used plasticizer whose environmental release poses significant risks to ecosystems and human health. This study systematically investigated DBP adsorption on three common nanomaterials—titanium dioxide nanoparticles (n‐TiO2), multiwalled carbon nanotubes (MWCNTs), and carboxylated MWCNTs (MWCNTs‐COOH)—using ...

Compaction effects on crop yields in Vertisols: Transient under wet years

open access: yesAgrosystems, Geosciences & Environment
Soil compaction commonly impacts productivity in Australian cotton production systems. A field experiment conducted during the 2019–2020 season showed that compaction decreased lint yield by 27%.
