In this article, the mechanical parameters of characteristic soils of the city of Brasília are obtained, calibrated and validated for the Hardening Soil (HS) model, based on laboratory and field test results obtained in previous research studies conducted in the Experimental Field of the University of Brasília (CEGUnB). The strength and compressibi...

The pozzolanic reactions, responsible for the resistance of soil-lime blends, are endothermic. As such, increasing the curing temperature in turn increases the strength of lime-stabilized soil. Recent research has shown that there is a maximum limit to the resistance of a specimen, based on its curing time. This study aims to predict the maximum tensile...

The dynamic cone penetrometer (DCP) is a widely used in-situ device to determine the engineering properties of soils. This paper reports a meta-analysis of laboratory calibration studies to establish a relationship between the rate of penetration and relative density for sands. Fourteen (14) different sands from different geographic and geological setti...

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...
