Reduction of shrink-swell potential with EPS inclusion

Illuri, Hema K. & Nataatmadja, Andreas (2007) Reduction of shrink-swell potential with EPS inclusion. In Ameratunga, Jay, Taylor, Brett, & Patten, Matthew (Eds.) 10th Australia New Zealand Conference on Geomechanics 2007 : Common Ground, 21-24 October 2007, Brisbane.


This paper describes how three reconstituted soils with PI ranging from the laboratory by mixing fine sand and sodium rich bentonite. A series these soils, which were mixed with recycled Expanded Polystyrene (EPS). By varying the EPS content, compaction tests results indicated that there in the optimum moisture content of the soil – EPS mixes, but with significant reduction in the maximum dry density due to the soil replacement The inclusion of EPS beads significantly reduced the free swell and swell In addition, the test results also showed that the inclusion of recycled volumetric shrinkage and crack intensity of expansive soils. The technique is thus showing great promise in sustainable construction.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
