Long-term effects of a one-time application of flue gas desulfurization gypsum on the soil pore structure in sodic paddy fields

open access: yesAgricultural Water Management
Saline–sodic soil suffer from a high content of exchangeable sodium ions in the soil colloid and the poor air and water permeability of the soil pore structure.

Industrial Symbiosis as a Neglected Opportunity in Industrial Decarbonisation Pathways: Qualitative Insights From the Australian Manufacturing Sector

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Industrial symbiosis (IS) represents a key strategy for industrial decarbonisation (ID) by converting one industry's waste into valuable inputs for another, reducing emissions and resource extraction. Scientific studies have explored the concept, implementation approaches and theoretical foundations of IS.

Gypsum as an ameliorant for revegetating salt-affected ore refining residues [PDF]

open access: yes, 1994
Revegetation on mine sites and mine wastes in Western Australia commonly has to deal with salt-affected substrates (the generic term substrate includes soils, saprolite, overburden and residues, all of which can be media for plant growth on mine sites ...

Enhancement of the Plant‐Accessible Phosphate Fraction in Sewage Sludge Ashes by Na+ or K+ Addition Prior to Combustion

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

The effects of cracks on the movement of Ca+2 within gold refining residue [PDF]

open access: yes, 1997
Gold refining residue is alkaline (pH> 9), saline (EC1:5: 800- 1100 mS/m) and sodic (ESP>60) (Ho et al., 1998). These chemical properties have a detrimental effect on residue physical properties (hydraulic conductivity, bulk density, porosity).

Soil Chemical Parameters with the Use of Agricultural Gypsum and Effects on the Apple Tree Crop

open access: yesInternational Journal of Plant Biology, 2023
Using agricultural gypsum promotes nutrient descent and generates a less aggressive environment for roots, favoring their development and better use of water and nutrients.

Review and prospects of shear test of bolted rock joints

open access: yesDeep Underground Science and Engineering, EarlyView.
The laboratory shear test equipment, test method, and numerical simulation of bolted rock joints were summarized. The shortcomings and limitations of the current research were analyzed, and the research prospects were proposed. Abstract Rock bolting is a critical approach in geotechnical engineering for supporting weak rocks.

Numerical and experimental study on P‐wave propagation across a rock joint with different orientations

open access: yesDeep Underground Science and Engineering, EarlyView.
Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...
