This study compared the process of biotic and abiotic degradation of biodiesel in a clayey soil in a laboratory environment (ex situ) and infield environment (in situ). The experiment carried out ex situ had controlled temperature and humidity, while the experiment in situ was directly influenced by external factors such as rainfall and temperature. The...
View ArticleAlthough the dynamic load test technique has been developed for a long time, it became very popular in Brazil over the last 20 years (especially after the publication of Brazilian Standard NBR6122, in 2010). However, the site quality control of driven piles in respect to the resistant capacities remains with the practical application of the so-called &a...
View ArticleThe elastic constants obtained through conventional destructive (triaxial and resilience) tests can present great variability, even for soils with the same classification. Thus, a test is necessary to determine the elastic constants of soils in a reliable and replicable way. The ultrasonic technique is used to characterize rock and several construction ...
