It also investigates the geotechnical properties of seven paper mill sludges for use as the impermeable barrier in landfill covers: water content, specific gravity, organic content, consolidation characteristics, shear strength and compaction test. Test pads were constructed to simulate a typical landfill cover with paper sludge and clay as the
This study investigates the geotechnical properties of seven paper mill sludges. Paper mill sludges have a high water content and a high degree of compressibility and behave like a highly organic soil. Consolidation tests reveal a large reduction in void ratio and high strain values that are expected due to the high compressibility.
The objective of this research is to contribute to the development of new geotechnical materials, by evaluating geotechnical properties of a paper mill sludge from an industry located in Porto Alegre, southern Brazil. For the evaluation, hydraulic conductivity with different molding moisture contents, a compaction test, organic matter, specific

This paper summarizes the geotechnical properties of IP''s paper sludge obtained from the feasibility studies, primarily hydraulic conductivity. It includes the effects of freezethaw and biologic degradation on sludge hydraulic conductivity. Design and construction considerations for a landfill cover using paper
Geotechnical properties of paper recycling waste streams IGS 3 ECSMGE2019 Proceedings deinking. The sludge used in this study comes from the latter process.
Geotechnical properties of seven paper mill sludges are studied. A high water content and a high degree of compressibility characterize the paper mill sludges, which behave like highly organic soil. Consolidation tests show a large reduction in void ratio and high strain values that are attributed to the high compressibility.

In: Proc. of the Fifth International Workshop on the Use of Paper Industry Sludges in Environmental Geotechnology and Construction, 2325 May, Manila, Philippines, pp. 50 57 .
In this paper geotechnical properties of paper mill sludges such as Atterberg limits, organic content, specific gravity, standard compaction, hydraulic conductivity, and unconfined compressive strength were tested for reuse of paper mill sludges for waste landfill cover liner.
batches of paper sludge were used for this study: the first one was found to be of a water content of 57%; the other two were of a water content of 3032% which is consistent with the suppliers product datasheet. The presented tests on the geotechnical properties of the material are based on the latter two batches.
In some cases, paper sludge covers can be marginal in terms of hydraulic conductivity or slope stability, thus, a monitoring strategy should be specified to evaluate performance compliance. The unique geotechnical behavior of paper sludges includes large settlement strains or large reductions in void ratio which induce decreases in hydraulic conductivity and increases in undrained shear strength (which
The sludges obtained from Slovene paper mills were examined for their geomechanical, chemical and sealing properties, as well as for their microbiological stability. The results of preliminary geotechnical studies of paper sludges indicate the expected relatively low strength properties (14 kPa lt; c lt; 81 kPa), high compressibility and a low coefficient of permeability * 10 10 lt; k lt; * 10 11 .

Dec 13, 2016#0183;#32;This paper presents a comprehensive review of reported field and laboratory investigations and theoretical work concerning the geotechnical behaviour/properties of water treatment residue (WTR), biosolids and sewage sludge materials, which are byproducts of municipal water and wastewater treatment processes.
The geotechnical properties of different organic materials including compaction, consolidation, hydraulic and thermal conductivities were analyzed. The obtained result is that both sludge and rice husk show low dry density, specific gravity, thermal and hydraulic conductivities.
