Effect of the Porosity/Cement Ratio on the Compression of Cemented Soil
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 138, Issue 11
Abstract
The compression behavior of an artificially cemented soil was analyzed by the adjusted porosity/cement index using a correlation established in the recent literature. It was found that for each value of this index, defined as the ratio of porosity to the volumetric cement content, there was a unique normal compression line (NCL). The NCLs of the cemented specimens for each adjusted porosity/cement index did not converge with the NCL of the uncemented silty sand at large stresses, but reached a line parallel to it. The NCL of the cemented sand plotted further from the NCL of the uncemented sand as the porosity/cement index decreased.

Acknowledgments
The writers wish to thank Professor Coop and the Imperial College team to allow them to carry out the isotropic compression tests when time was pressing. A word of gratitude is also given to the FEUP Ph.D. student, Miguel Amaral, who made some additional tests that gave more consistency in the results presented herein. This research was developed under the activities of FCT (Portuguese Foundation for Science and Technology) research unit CEC, in FEUP (PTDC/ECM/ 099475/2008), and financed by the European Community (QREN/UE/FEDER), Operational Program for Competitive Factors “COMPETE”. The first writer had the financial support of Ph.D. Grant SFRH/BD/29346/2006.
