This book was released on 2011 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, effects of cement content and curing time on the compressive stress-strain relationship and California bearing ratio (CBR) value of artificially cemented sand cured up to 7 days was investigated. The CBR study was focused on investigating the sensitivity of this non-destructive test to measure the changes in the compacted cemented sand properties during construction (limited curing time). The cement content in the cemented sand was varied up to 6 % by weight. The strength, modulus, and unit weight of the artificially cemented sand varied from, 60 to 1250 kPa, 14 to 290 MPa, and 15.98 to 18.33 kN/m3, respectively. The CBR values for cemented sand, compacted using the standard proctor method, varied from 8 to 230 %. Compressive stress-strain relationship of cemented sand was represented by a non-linear relationship. Relationship between compressive properties of cemented sand and the CBR was also investigated. The variation of compressive strength, modulus, and CBR values with curing time were represented using hyperbolic relationships. Finite element method (FEM) was used to model the CBR test, based on the data obtained from the unconfined compression tests for 1.5, 3, and 6 % cemented sand. In the FEM analyses the cemented sand was modeled using linear elastic-perfectly plastic constitutive relationship with Mohr-Coulomb failure criteria. The ratio of predicted to measured CBR values varied from 0.67 to 1.31.

This book was released on 2005-09-12 with total page 3742 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 16th ICSMGE responds to the needs of the engineering and construction community, promoting dialog and exchange between academia and practice in various aspects of soil mechanics and geotechnical engineering. This is reflected in the central theme of the conference 'Geotechnology in Harmony with the Global Environment'. The proceedings of the conference are of great interest for geo-engineers and researchers in soil mechanics and geotechnical engineering. Volume 1 contains 5 plenary session lectures, the Terzaghi Oration, Heritage Lecture, and 3 papers presented in the major project session. Volumes 2, 3, and 4 contain papers with the following topics: Soil mechanics in general; Infrastructure and mobility; Environmental issues of geotechnical engineering; Enhancing natural disaster reduction systems; Professional practice and education. Volume 5 contains the report of practitioner/academic forum, 20 general reports, a summary of the sessions and workshops held during the conference.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of a cementing agent on the mechanical behavior of a quartz sand and a natural silt were studied with drained triaxial tests. The cementing agent was a cement fly ash slurry, and the specimens so formed were weakly cemented. The higher stiffness of the cemented specimens can be explained by the presence of structure, but it may not be always valid to equate structure to the contribution of a cementing agent. Special zero effective confinement tests were conducted to directly measure the contribution of bonding between grains to the strength and stiffness of the two cemented soils. Test results unambiguously indicated the occurrence of progressive bond breakage prior to failure. At a stress state remote from failure, a cemented soil has lower dilatancy relative to the parent soil because of the presence of significant bonding. However, bond breakage occurring at higher shear stress led to a more dilatant soil fabric. The shear strength data followed a curved failure surface that merged back, at high stress, to that of the parent soil. This feature can be captured by a failure function that models the contribution of a cementing agent to strength as two parts, true bonding between soil grains and increase in dilatancy at failure. Both parts degrade with increasing effective confining pressure, but at different rates.
