The Performance of a Sand Reinforced with Coconut Fibers Through Plate Load Tests on a True Scale Physical Model

September 18, 2018
The use of recycled materials has experienced a growing global interest in the last decades. Products like natural fibers are being studied to replace synthetic fibers in some applications because they are renewable resources that have a lower cost. Fibers can be used as reinforcement for covers of landfill sites, landfilling over soft soils, and evapotranspirat...

Porosity Changes of Compacted Soil Percolated with Acidic Leachate

October 02, 2018

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...

Effects of Spatial Variability on Slope Reliability: A Hypothetical Case Study

September 18, 2018
Due to the complexity and uncertainty involved in mass movements, it is not possible to predict their occurrence with accuracy. This uncertainty is due to the space-time variability of physical soil parameters and processes, which determine the boundary conditions of the problem. In this study, we analyzed the influence of spatial variability of the parameters t...

Effects of the Addition of Dihydrate Phosphogypsum on the Characterization and Mechanical Behavior of Lateritic Clay

May 16, 2018
This paper presents the effect of adding dihydrate phosphogypsum, which is a byproduct of the production of phosphate fertilizers, on the mechanical behaviour of a lateritic clay typical of Brazil’s Midwest region. Because of the distinction of the mechanical behaviours of both materials, laboratory experiments were conducted with soil, phosphogypsum and mixture...
