Effect of peat solidification on macronutrients in soils associated with palm oil plantation in peat area
… are factors that affect the chemicals in the peat soil stabilization through leaching. The study aims to identify the concentration of elements and nutrients on peat solidification of cement (OPC), fly ash and bottom ash. Lab scale physical model was set up in different conditions with …

Influence of post-cyclic loading on hemic peat
Construction on peat soils has proven to be a challenging task to civil engineers since this soil type has a significant issue that arises from common problems construction of roads, housing and embankment construction with regard to peat are stability, settlements and major problems were …

Geotechnical Properties of Peat and Related Engineering Problems
… properties of Middleton and James Bay peats were obtained. Such results will provide an idea about the order of magnitude of geotechnical parameters as well as the behavior of these parameters under changing conditions and with time. (Abstract shortened by UMI.).

The performance of polyurethane grout to stabilise hemic peat
Peat has always considered as a challenging ground for any form of construction due to its engineering characteristics such as high short-term settlement, prolonged long�term post construction settlement and high natural moisture content exceedingly more than 100%. Numerous construction materials …

An Isotopic Analysis of Carbon Dynamics in Sphagnum Peat
Methane and carbon dioxide produced in peatlands can be held temporarily in dissolved surface waters and accessible to aquatic plants. The primary peat building plant in northern peatlands, Sphagnum moss, grows in these dissolved carbon rich waters. Understanding Sphagnum carbon cycles is key for …

Fate of natural and anthropogenic particles in peat bogs
… fate of anthropogenic and natural particles in peat bogs, to see which geochemical processes can affect the suitability and accuracy of peat bogs as archives of atmospheric deposition, and also the effects of these inputs on the bog ecosystem. To test whether peat bogs are accurate archives of …

Koalisi Lahan–Gambut: Assembling Peat–Land Futures in Kalimantan
… colonial and postcolonial histories, the peatlands of Kalimantan have been not only politically contested spaces but also sites of ontological struggle. From transmigrasi programs to Suharto’s Mega-Rice Project and most notably today’s carbon offset regimes, peat has been transformed into …

Application of the peat archive as tool in environmental chemistry
Ombrotrophic peat bogs are natural archives of atmospheric deposition of pollutants. Therefore, peat profiles can be used to study the chronology of environmental contamination with harmful pollutants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and per- and …

Effect of reconstituted method on shear strength properties of peat
Peat is an organic soil contains more than 75% organic content. Shear strength of the soil is one of the most important parameters in engineering design, especially during the pre-construction and post-construction periods, since used to evaluate the foundation and slope stability of soil. Peat …

Performance of hot mix asphalt using peat modified asphalt binder
… conducted to investigate the use of parit Nipah peat (PNpt) to be mixed with asphalt, both of unaged and aged conditions to improve the performance of asphalt mix. The physical properties, storage stability and rheological properties of base asphalt and PNpt modified asphalt (PNpt.M.A.) were …

Static and Dynamic Performance of Biochar Enhanced Cement Stabilised Peat
Peat is a type of soft soil with very high organic and water contents. It lacks any kind of structure, which makes it extremely compressible and weak. These are highly undesirable physical characteristics when considering a site for construction, as they significantly increase the risk of large …

IMPACTS OF TROPICAL PEAT-FOREST SMOKE: URBAN PM2.5 AND TOXICITY IMPLICATIONS
… better address the impacts of recurrent tropical peat-forest (PF) burning in the Maritime Continent on regional air quality and public health, this thesis characterizes chemical composition of urban PM2.5. Urban PM2.5 are systematically classified to smoke-dominant (SD) vs. non-SD samples. In-situ …

Spatial variability of peat subsidence in Southeast Asia by land use
… variations in environmental parameters such as peat subsidence in two dimensional space, but also to understand the factors governing these variations. With the deforestation and drainage of wetlands in Southeast Asia, there has been a gradual sinking across large areas of land (i.e. …
