Stabilisation with geogrids for transport applications – selected issues [PDF]

MATEC Web of Conferences, 2019
Stabilisation is defined as improvement of the mechanical properties of an unbound granular material by including one or more geosynthetic layers such that the deformation under applied loads is reduced by minimizing soil particle movement. Paper discuss

Reducing Soil Permeability Using Bacteria-Produced Biopolymer

Applied Sciences, 2021
The building of civil engineering structures on some soils requires their stabilisation. Although Portland cement is the most used substance to stabilise soils, it is associated with a lot of environmental concerns.

Sustainable Soil Stabilisation Using Plastic Waste [PDF]

E3S Web of Conferences
The practice of soil stabilisation is popular to increase the bearing capacity and strength of weak subgrade soils. Traditional stabilisers like lime and cement enhance soil performance, but their sole use can result in higher costs and environmental ...

Geotechnical viability of sand, cement, and binary stabilisation of soils in the western Niger Delta; An example of Warri City, Southern Nigeria

Journal of the Geological Survey of Brazil
The pavement performance of superficial soils in southern Nigeria is in decline, most notably due to the use of inferior pavement materials and poor soil conditions.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

FEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Effect of moisture content on alkali-activated stabilisation of expansive soils

Case Studies in Construction Materials
This study presents a comparative evaluation of two slag-based alkali-activated stabilisation approaches for expansive soils, distinguished by the initial moisture contents of the treated soil: (i) optimum moisture content, OMC, (in a moist state) and ...

Pyramidal Structures on Yttria‐Stabilized Zirconia after High Temperature Exposure at 1500°C: New Features on an Old Material

Advanced Engineering Materials, EarlyView.
New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...

Efficacy of expansive soil stabilisation using un-calcinated Kaolinite-Based Alkali-Activated binders

Cleaner Materials
In recent years, alkali-activation and geopolymerisation have emerged as sustainable alternatives for stabilising expansive soils, traditionally treated with lime or cement. While most studies focus on high-temperature-processed materials such as fly ash,
