Abstract—Expanded polystyrene (EPS) geofoam is often used in below ground applications in geotechnical engineering. A most recent configuration system implemented in roadways to protect lifelines such as buried pipes, electrical cables and culvert systems could be consisted of two EPS geofoam blocks, “posts” placed on each side of the structure, an EPS block capping, “beam” put atop two posts, ...

The work aims to analyze the effect of partial replacement coarse aggregate by expanded polystyrene (EPS) in production hollow blocks, a type concrete block. Substitution levels, volume, 0% (reference), 5%, 10%, 15%, 20%, and 25% were tested. following tests performed: granulometric composition, specific mass, unit surface analysis tests, absorption, mass determination, dimensional compressive ...

Expanded polystyrene (EPS) is a material that widely used in energy absorbing applications, especially helmets, despite its non-renewable origin. Cork and derivatives, however, are proposed as substitute for foam due to their renewable origin easy recyclability. In spite of the low-environmental footprint cork there insufficient data on mechanical behaviour. Consequently, under dynamic quasi-st...

Concerning energy improvement of existing façades, a favourable system involves prefabricated multilayer panels, made internal insulation core and outer textile reinforced concrete layers. It is convincing alternative to external thermal composite systems (ETICS) ventilated it meets all the requirements for façade systems. The main advantage possibility toapply panel using crane, without any sc...

Expanded Polystyrene (EPS) is a lightweight, malleable, adjustable strength material with good cushioning properties. This paper introduces the concept of diameter-thickness ratio and high-thickness to analyze impact force duration data tests different thicknesses EPS plates sand cushion layers under environments, which shows that within range thickness can be withstood by structure shed cavern...

In this paper, a new anisotropic material concept namely composite foam is proposed as an alternative to next generation helmet liners which can potentially reduce head rotational accelerations. The Layered Composite foam concept comprises of foam layers with different densities which are glued to each other in a parallel or series configuration. Initial experiments such as static combined shea...

By Heming Zhang Alwin, M.S. Washington State University December 2002 Chair: John C. Hermanson Structural insulated panel (SIP) use in residential building began in the 1950s. Over the last two decades, greater SIPs usage has been encouraged by many factors. ICBO ES provides “Acceptance Criteria for Sandwich Panels AC04” for sandwich panels recognition. The criteria require that full-scale pane...

Two national metrology institutes have conducted an international interlaboratory comparison on thermal conductivity for two thermal insulation reference materials. The Laboratoire national de métrologie et d’essais (LNE), France, and the National Institute of Standards and Technology (NIST), United States, present measurements obtained by the guarded-hot-plate method. The study involved two ma...

Abstract Expanded polystyrene (EPS) geofoam is one of the lightweight materials used in civil engineering applications. Present study deals with application retaining wall as a backfill. In this study, two-dimensional finite element software to simulate geofoam. A 6m height considered. Lateral pressures and surface settlements are examined for various orientations Orientations include upper tri...
