We created a novel air-filled bicycle helmet. The aims of this study were (i) to assess the head injury mitigation performance proposed helmet and (ii) compare those results against an expanded polystyrene (EPS) traditional Two types subjected impacts in guided vertical drop tests onto flat anvil: EPS helmets (Bumpair). maximum acceleration value recorded during test on Bumpair was 86.76 ± 3.06...

The construction industry is growing fast alongside the growth of economy and population. As one major building materials, brick in high demand for purposes. continuous will eventually lead to a shortage raw materials long run, such as sand Ordinary Portland cement. This issue could be resolved by utilizing waste Expanded Polystyrene (EPS) beads Silica Fume (SF), replacement cement production b...

Abstract Expanded polystyrene (EPS) is a synthetic plastic used in various industrial and commercial applications. EPS popular for its unique physical properties, specifically insulating capabilities low density. These properties become problematic at the end of useful life as cannot be recycled with other conventional plastics. Though possible, recycling often practically or economically prohi...

The selection of insulation material and the determination optimal thickness are very important for saving energy ensuring thermal comfort. There numerous studies in literature determining optimum thickness. In these studies, conductivity coefficient (k) is taken directly from standardized tables calculated. real applications, k value varies depending on production conditions, density temperatu...

Expanded polystyrene (EPS) and corrugated paperboard (CPB) are used in many industrial applications, such as containers, shock absorbers or simply as inserts. Both materials pose two different types of environmental problems. The first is the pollution and resource consumption that occur during the production of these materials; the second is the growing landfills that arise out of the excessiv...

Usually, the corn cob is considered an agriculture waste. This natural and organic waste material may be used in the industry, in general, and in the building industry, in particular. The work presented in this paper was developed in order to give a contribution to the knowledge of this material, by attempting to describe and assess its macrostructure and microstructure, elementary chemical com...

Building on weak soils is very challenging in engineering projects, especially highway and railway projects. To overcome these problems, the construction of embankments abutments, it necessary to reduce settlement soil increase bearing capacity. This paper investigates characteristics expanded polystyrene (EPS) foam beads mixture as a lightweight material. EPS characterized lightweight, economi...
