Soil stabilization utilising wastepaper sludge ash
… used to modify certain engineering properties of soils for specific uses to conserve non-renewable natural resources.<br/><br/>In lime-stabilization of sulfate-bearing clay soils, there has been increasing concern over the damage caused by the expansion which is produced when sulfate-bearing soils …

Soil stabilization properties of flexible intruders
In many locations, soil is held in place by the roots of plants. When these plants are removed or die, the soil loses its cohesive strength and erodes away. We seek to create artificial soil stabilizers that use the same physical principles as the plant roots. To investigate how flexible materials …

SUCCESSION OF ARBUSCULAR MYCORRHIZAL FUNGI: CAUSES, CONSEQUENCES, AND CONSIDERATIONS
Arbuscular mycorrhizal fungi (AMF) are soil fungi associations with the majority of terrestrial plants. These fungi may affect a wide range of ecosystem processes from primary productivity to soil stabilization. Understanding the patterns and controls of AMF abundance during succession soil will be …

Geotechnical performance using alkaline activated fly ash for soil mixtures with and without polypropylene fibers
Soil stabilization is one of the well-known methods to treat problematic soils. Its advantages over soil replacement are that of low cost and fast implementation. Alkaline activation (geopolymerezation) of soft soils is a new technique that has been addressed recently to stabilize soft soils. …

Soil compaction of peat under the influence of electrokinetic stabilization (EKS) treatment
… Peat is considered as one of the problematic soil in construction projects all over the world, which covers about 4% land of the whole world while 8% of the total area of Malaysia and about (5.86%) of peat soil existing in Johor state. Low shear strength of peat may lead to massive loss of …

Estabilização de areia com cinza volante e cal; efeito do cimento como aditivo e de brita na mistura
Study on the stabilization of sand with fly ash and hidrated calcitic lime, and the effects of admixing portland cement and crushed stone on the compressive strength of the mix. In order to enhance fly ash role the soil chosen was a non-cohesive one - a uniform dune sand - which is not quite …

Using BCSA Cement to Repair Waterway Transportation Structures
… to choose the best mix design. Additionally, soil cements made with BCSA cement were compared to portland cement-based soil cements. These soil cements have applications for rapid repair of levees and earthen dams, but also for rapid soil stabilization. The results obtained prove that BCSA …

Stabilisation of sulphide rich soil: problems and solutions
… the findings from this thesis indicate that soil stabilisation with lime and GGBS is particularly effective for naturally occurring sulphide rich clay soils (such as the LOC) and is an environmentally friendly alternative to PC-stabilised soils.

Permanence and Life Cycle Performance of Biocementation Soil Improvement
… improve the engineering properties of granular soils through the generation of calcium carbonate minerals on soil particles surfaces and at interparticle contacts. The process can offer an environmentally beneficial alternative to conventional ground improvement methods, which have traditionally …

Estabilização de areia com adição de cal e cinza volante
… uniform sand. Timing at the action of fly ash, a soil with no cohesion, lacking of colloidal fraction, was chosen. This soil is not suitable for the usual processes of stabilization with portlant cement or lime. The fly ash - a residual material from the burning of pulverized coal - and lime, when …

Earth to Earth : reconciling earthen dwellings with eroding loess landform : the case of Loess Plateau in China
… with loess deposits, a type of highly erodible soil consisting of less than 20% clay. Loess soil has topped eroding hills and valleys and supported an earthen construction tradition in loess landform territories. The Loess Plateau in China has been suffering from heavy soil erosion. Soil erosion …

Effect of peat solidification on macronutrients in soils associated with palm oil plantation in peat area
Nutrients in the soil either from man-made fertilizers or natural 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 …
