To investigate the effect of particle size on mechanical properties of calcareous sand, a series of consolidated drained triaxial tests were performed on calcareous sand with different particle sizes. At a low effective confining pressure of 50 kPa, the shear peak strength increases with the increasing particle size. However, under a relatively large ef...
View ArticleSouth Americas topographic characteristics and available materials have led engineers to select earth or rockfill material for dams construction. However, there are tropical regions with high annual rainfall where the soil compaction above the optimum moisture must be studied in detail. This research presents the results of tests performed on compacted ...
View ArticleThis paper optimizes and compares the behavior of soil-cement compacted blends against several molding and climate conditions under optimum compaction and non-optimum compaction parameters. For this, an intensive laboratory study of silty soil samples treated with different percentages of high early strength Portland cement (PC) was investigated by a se...
View ArticleA constitutive model is proposed for describing the stress-strain behavior of saturated residual soils based on experimental observations from oedometer testing, triaxial and direct shear testing. The model is formulated within the classical theory of plasticity with a non-associated flow rule. In order to reproduce particular features of residual soils...
