In this review article, the authors present up-to-date developments on experimental, modeling and field studies on the role of subsurface colloidal fines on contaminant transport in saturated porous media. It is a complex phenomenon in porous media involving several basic processes such as colloidal fines release, dispersion stabilization, migration and fines entrapment/plugging at the pore con...

The paper presents the test results from investigation of nature and mechanical behaviour mudbricks ancient mudbrick wall Eleusis in Attica, Greece. remains preserved to date site are some largest Small fragments were taken laboratory for experimental investigation. Testing included index tests toclassify soil material made of, mineralogical analyses their fines’ content, testing suitable mater...

We examine the effectiveness of bonuses and fines in an ‘inspection game’ where an employer can learn the effort of a worker through costly inspection. Standard game theoretic analysis predicts that fines discourage shirking, whereas bonuses encourage shirking. In contrast, ownpayoff effects suggest that both fines and bonuses discourage shirking. In an experiment we find that fines are more ef...

The energy required to crush rocks is proportional to the amount of new surface area that is created; hence, a very important percentage of the energy consumed to produce construction aggregates is spent in producing non-commercial fines. Data gathered during visits to quarries, an extensive survey and laboratory experiments are used to explore the role of mineralogy and fracture mode in fines ...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand-fines mixtures under cyclic loading. results triaxial tests conducted Hostun sand with varying amounts (0–20%) types (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method, consolidated...

Abstract The paper presents an experimental study on the effect of plastic fines content undrained behavior and liquefaction susceptibility sand–fines mixtures under monotonic loading. results triaxial compression tests conducted Hostun sand with varying amount (0–20%) type (kaolin calcigel bentonite) are presented. specimens were prepared different initial densities using moist tamping method ...

In terms of storage capacity and containment efficiency, deep saline aquifers are among the best candidates for CO2 storage. However, salt precipitation in the wellbore vicinity and fines mobilization ensued from in situ mineral dissolution could impair CO2 injectivity and reduce the quality and capacity of deep saline reservoirs for CO2 storage. The mechanisms of salt precipitation and its imp...
