Sample quality has a direct influence on the results of geo-mechanical parameters obtained in laboratory and in situ tests, potentially causing serious technical and economic consequences. In the study of soft soil behavior using laboratory tests, it is important to evaluate, and be able to quantify sample quality, and if necessary and possible, to corr...
View ArticleMicrostructural parameter assessment of reservoir rocks is extremely important for oil companies. In this regard, computerized X-ray microtomography (μ-CT) has proven to be an exceptionally useful methodology for the analysis of these rocks, since it provides significant microstructural parameters, such as porosity, permeability, and pore distrib...
View ArticleA root pile is an injected type of pile (cast-in-place with pressure, with very distinct construction aspects from the known micropile type). Those piles are installed by using distinct injection pressures up to 500 kPa during the mortar shaft formation. The executive control of root piles is usually carried out by static load tests, requiring a costly ...
View ArticleIncreased food production results in the development and application of agrochemicals to control weeds, which can affect agricultural production. Pesticides contaminate the environment and change soil and water quality. Therefore, to improve the understanding of the adsorption mechanism of 2,4-dichlorophenoxyacetic acid (2,4-D) in aluminoferric red oxis...
