The main goal of this paper is to evaluate the chemical and mineralogical composition of a compacted residual clay soil with the addition of Portland cement and under different compaction conditions to observe and to understand the chemical and mineralogical changes that these structures undergo. Results of chemical and mineralogical composition of compacted spe...

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 ...

<p>This paper evaluates porosity changes in compacted soil subjected to acidic leachate percolation through different dry unit weights. The porosity of compacted soil is presented in different nominal porosities or dry unit weights (41.9% and 15.5 kN/m3, 43.8% and 15.0 kN/m³, and 45.7% and 14.5 kN/m³) percolated with a sulfuric acid solut...

<p>The study evaluated, through a series of permeability and diffusion tests, the hydraulic and the attenuation behavior of a compacted clayey soil, with and without the addition of Portland cement (0 to 2%). To evaluate the diffusive response, the specimens were subjected to a vertical static load (100 to 500 kPa), simulating the action of a waste mass, a...
