Density and Strength Properties of Sand-Expanded Polystyrene Beads Mixture
GeoCongress 2008, 2008Expanded Polystyrene ƒ EPS ≈ beads was utilized to develop a new geotechnical material, sand-EPS beads-mixture (SEM). Density tests, direct shear tests and compression tests were conducted to evaluate the density and strength properties of the SEM. Direct shear tests were conducted under 4 different vertical stresses (32.7, 50, 75, 100kPa).

Evaluation of alternatives to expanded polystyrene beads for mosquito control
Journal of Applied Entomology, 2013AbstractExpanded polystyrene (EPS) beads have been shown to be an effective tool for controlling immature stages of mosquitoes, as well as preventing oviposition by adults. Polystyrene does not biodegrade quickly, resulting in some concerns about its effect on the environment.

AbstractIncreased energy absorption and load result when the contact area between an object and a foam cushion is less than the foam area because of an increased foam deformation volume (i.e. “Load Spreading”). The deformed volume is trapezoidal (i.e. not prismatic) and is a function of the foam dimensions and the object geometry.

The Relevance of Expanded Polystyrene Beads for Ground Improvement: A Review
2021An expanded polystyrene (EPS) beads are a lightweight synthetic material that is manufactured daily as a packing material. This study describes the engineering and mechanical behavior of the EPS beads under the actions of stress. The influence of size (diameter) and density of EPS beads on a stress–strain behavior have been well explained in the study.

Experimental Studies on Bottom Ash and Expanded Polystyrene Beads–Based Geomaterial
Journal of Hazardous, Toxic, and Radioactive Waste, 2016AbstractBottom ash is a by-product produced from burning of pulverized coal in thermal power plants. The increasing production of bottom ash and its disposal in an eco-friendly manner is a matter of concern. This paper concisely describes the suitability of bottom ash to be used in civil engineering applications as a way to minimize the amount of its ...

Water Stability of Light Weight Soil Amended with Expanded Polystyrene Beads
Geotechnical and Geological Engineering, 2019To reveal the durability of light weight soil ground under water environment conditions, the influence laws of soaking time and dry–wet cycle times on mechanical properties of light weight soil are researched by density tests, unconfined compressive strength tests, water absorption tests and mass loss rate tests.

Properties and Applications of Cement-Treated Sand-Expanded Polystyrene Bead Lightweight Fill
Journal of Materials in Civil Engineering, 2013AbstractTo mitigate settlement problems associated with bridge approach embankments over soft soil, a newly-developed lightweight material was proposed in this study. This lightweight material consisted of expanded polystyrene beads, the hydraulic sand from the Yangtze River, and cement.

Magnetization of large polystyrene peptide beads for capturing and expanding cancer cells
Journal of Magnetism and Magnetic Materials, 2003A method is described for preparation of large magnetic polystyrene beads coupled with peptide ligands for surface receptors of lung cancer cells. We have demonstrated the feasibility of using these magnetic peptide beads for capturing and enriching lung cancer cells spiked into blood. These magnetic peptide beads potentially can be used to efficiently
