The use of soil-bentonite mixtures for sanitary landfill liners with the purpose of retaining pollutants is becoming very common. This work shows the results of hydraulic conductivity and shear strength tests performed with soil-bentonite mixtures with bentonite contents of 3%, 5% and 7%. Additionally, shear strength test results carried out with a mixt...
View ArticleThe assessment of problems of imperfect, damaged, pile groups is scarce in the geotechnical literature. Besides, techniques of assessing the performance of the foundation system once a defect is found are seldom presented, as well as real examples of the behavior of large scale imperfect foundations after their remediation. Therefore, this paper has ext...
View ArticleThe ash of rice rind is a pozzolanic material that reacts with the calcium hydroxide (Ca (OH)2) forming bonding composites, when finely worn out and in water presence. Considering this behavior, the objective of the present work was to evaluate the potential use of this residue in the enrichment of the content of pozzolanic materials of a tropical soil ...
View ArticleIn the case of skyscrapers, the suitable bearing surfaces occur at considerable depth in rock formations, and when it is uneconomical to excavate the overlying weak material, socketed shafts are required for the foundations. In selecting a suitable foundation system, several factors must be taken into consideration. In this article problems associated t...
