Abstract: The adjusted porosity/cement index η/(Civ)a showed to be an interesting empirical rational dosage methodology for soil-cement purposes as it inputs into a single parameter the role of the compactness and the amount of ...

Abstract: The search for innovative solutions that reduce the need for exploitation of natural resources and make use of residues to produce alternative construction materials is a necessity. Eggshell residues are a solid waste ...

Abstract: Fine-grained soils that expand when in contact with water can be a major issue in some geotechnical situations, but the soil can be stabilized through chemical means by hydrated lime incorporation. However, there is not ...

Abstract: The employment of industrial by-products with pozzolanic properties (e.g., fly ash) is a viable technique for soil stabilization purposes when a more advantageous environmental performance is sought. For routine ...

Abstract: Soil mechanics traditionally have focused on studying pure clays and clean sands. However, natural soils and other geomaterials usually do not fall into these two classes. Most geomaterials are a complex matrix of fines ...

Abstract: Aspects related to differences in the behavior of plate load tests (PLT) bearing on highly porous, lightly bonded weathered clay in its natural structured and dynamically compacted states are addressed in this paper. Dynamic ...

Abstract: Sulfate-rich dispersive soils are worldwide responsible for damaging earthworks, such as roadway roadbeds and embankments. One of the causes for such behavior is the high amount of exchangeable sodium ions adsorbed on their ...

Abstract: Recent disasters involving upstream raised tailings dams in Brazil have caused regulatory agencies to prohibit the construction of new upstream dams and demand the decommissioning of existing ones. As such, new alternatives ...

Abstract: Lately, dry stacking of filtered tailings has emerged as a safer alternative to traditional slurry disposal in ponds as it comprehends the compaction of the unsaturated cake to form piles. A cementing agent can be added ...

Abstract: The improvement of soils that are not suitable for a particular purpose through techniques that combine densification and the incorporation of portland cement have been extensively done for decades in spite of the poor ...
