Abstract

This paper describes how three reconstituted soils with PI ranging from 22% to 53% were prepared in the laboratory by mixing fine sand and sodium rich bentonite. Recycled EPS beads were subsequently mixed with the Soil-Bentonite (SB) mixes to form Soil With EPS (SWEPS) composites. A series of free swell, shrinkage and cracking tests were performed on these new lightweight geomaterials. Results so far show that the inclusion of EPS beads significantly reduces the severity of volumetric change and cracking of the soils. The proposed technique is thus showing a great promise in sustainable construction through the possible utilization of unwanted materials in earth structures.

Impact and interest:

Citation countsare 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.
