.... In this study, the feasibility of utilising alkaline Class-F fly ash (FA) to assist XG in reinforcing acidic soils was evaluated through proctor compaction, unconfined compression, and one-dimensional consolidation. With the increasing soil acidities, the beneficial effect of FA on the geotechnical performances...

... loading. This paper presents an experimental study to investigate the micromechanical interactions of clay particles. Kaolinite samples were compacted to high vertical stresses and granulometry laser tests were carried out to investigate particle agglomeration. Samples were compacted in a dry state...

...G. Shahin; G. Buscarnera This study examines the role of boundary friction in promoting heterogeneous compaction in soft rock specimens loaded at high confining pressure outside the domain of compaction localisation. An elastoplastic constitutive model characterised by tunable hardening/softening...

...B. Scott; M. Jaksa; P. Mitchell Rolling dynamic compaction (RDC) is typically used for improving ground in situ or compacting fill in thick lifts. In many project applications, the effects of RDC are verified by way of testing that is undertaken pre- and/or post-compaction. This study presents...

... behaviour of compacted volcanic soils, which forms the purpose of this study. The behaviour of volcanic soil was evaluated using mineralogical characterisation tests, thermogravimetric analysis, compressibility, direct shear, water-retention curves and distribution of pores in the structure. The results...

...R. B. Saldanha; J. E. C. Mallmann; N. C. Consoli Compacted coal fly ash–carbide lime (two industrial by-products) blends have great potential application in geotechnical earthworks such as sub-base and base of pavements, beds of pipelines and spread footings, embankments and in erosion control...

...L. Morales; E. Romero; C. Jommi; E. Garzón; A. Giménez The effect of ageing on the small-strain shear stiffness of compacted silty-clayey sand following a ‘soft’ biological treatment is discussed. Samples were prepared by static compaction, adding urea-degrading bacteria to the compaction water...

...G. J. Burton; D. Sheng; C. Campbell The microstructure of compacted clay plays an important role in its hydraulic and mechanical behaviour. However, little experimental evidence is available for high-plasticity clay compacted on the wet side of the standard Proctor optimum water content...

... at an intended degree of compaction D_c = 100%, in order to investigate the relationship between particle strength and monotonic shear strength. Samples with intended degrees of compaction D_c = 85% and 90% were also tested at σ ′ c = 50 and 100 kPa in order...

...P. Harutoonian; C. J. Leo; S. Castellaro; J. J. Zou; D. S. Liyanapathirana The non-invasive measurement of horizontal to vertical spectral ratio (HVSR) of microtremors is proposed as a means to evaluate field compaction. The HVSR technique is a surface wave method that is quite distinct from...

...C. M. Sands; H. W. Chandler This article presents a novel model of the compaction of loose sand, or other granular material, incorporating two dilatancy terms. One is negative, reflecting the general tendency of an assembly to collapse under a combination of shear stress and pressure. The other...
