Exposure of geomaterials to acid leachates may cause chemical species desorption, mineral dissolution, and metal leaching. This study seeks to understand the changes in the physicochemical composition of liquid extracts resulting from the exposure of four different geomaterials (uniform fine sand, basalt residual soil, kaolin, and bentonite) to a blank solution ...

Soil nailing has proved to be an efficient and cost-effective stabilization technique, consisting in installing passive reinforcement in the soil that provides the material with tensile and shear strengths. The fundamental parameter in analyzing the mechanical behavior of this type of structure is the frictional resistance of the soil-nail interface, denominated...

Ultrasonic longitudinal wave velocity (Vp) and durability are characteristics largely determined in geotechnical evaluations. These properties are useful in the analysis of weathered rocks because they usually have good relationships with physical and mechanical properties of rocks. Additionally, the tests to obtain these parameters are easy to perform. However,...

Geocell is a tridimensional confinement structure used for soil reinforcement, which significantly improves the performance of foundation systems. Aiming at a more sustainable engineering project and promoting a correct destination of a residual material, an alternative to fill the geocell is through the use of precious gem processing waste. The performance of g...
