Thick wall (6.6 mm wall thickness) plastic samplers, 97.2 mm in internal diameter (area ratio of 29%), 700 mm in length (length of soil sample 640 mm), with a cutting edge angle of 23°, without clearance and with a sampler head have been used to collect very soft clay samples at Sarapuí II test site. Very good to excellent an...
View ArticleBiodegradation in residual basaltic soil contaminated by diesel fuel and biodiesel was assessed by three different techniques comprising natural attenuation, bioaugmentation, and bioventing. The soil was described in terms of its
physicochemical and microbiological characteristics, showing favorable bioremediation conditions. Natural attenua...
Soil - tire mixtures have been recently used as construction materials in civil engineering projects. In this research, a number of undrained triaxial tests were carried out on the compacted clay-tire mixtures and their behaviors were compared with behavior of pure clays. The results of the tests indicate that adding more than about 20%-30% tire to the ...
View Article. One of the most important morphological characteristics of expansive soil is contracting and fissuring during
drying and swelling during wetting. Soils that change volume when inundated with water require extra care, whether they
are used in agriculture, engineering or both. In this paper, conventional and suction-controlled oe...
