Lightweight sand–EPS soil (LSES) is regarded as a kind of sustainable geomaterial for providing way to reutilize fast-growing waste expanded polystyrene (EPS) packages. It usually applied in marine geotechnical engineering solve the excessive settling soft ground or bumps at bridge heads due its merits such low density, high strength, and adjustability. Aiming investigate dynamic shear strength...

The effect of 2, 4-dinitrophenol (DNP) on the extracelluar polysaccharides (EPS), cell surface charge, and the hydrophobicity of six marine bacterial cultures was studied, and its influence on attachment of these bacteria to glass and polystyrene was evaluated. DNP treatment did not influence cell surface charge and EPS production, but had a significant effect on hydrophobicity of both hydrophi...

Cemented backfill is one of geomaterials which is used at a high volume to serve a variety of geo-infrastructure systems, e.g., embankments, retaining walls and approach abutments, and involves the solidification of soil or similar fine aggregate through the addition of a controlled amount of cementitious materials, such as Portland cement, fly ash or lime. A certain volume of expanded polystyr...

Yapılan bu çalışmada, Isparta İlinde elma muhafaza amaçlı kullanılan 60 adet soğuk hava deposu araştırma materyali olarak belirlenmiştir. Soğuk sahipleri ile yapılan görüşmelerde bölgede depolarının %78.33’ünün sadece depolama kullanıldığı; geriye kalan %21.67’sinde ise haricinde yaz döneminde kiraz, kayısı, şeftali ve erik gibi meyvelerin kısa süreli depolamalarının yapıldığı İncelenen depolar...

In this study, in order to observe the mechanical and physical properties of normal screed, sandy-lightweight screed lightweight samples, expanded polystyrene (EPS) was used as fine aggregate systems produced by replacing sand at 100%, 50% 0% weight. Samples cement dosages 250, 300, 350 kg/m3 were for screeds, screeds screeds.
 Unit weight, water absorption capacity, flexural strength, com...

Social motility (S motility), the coordinated movement of large cell groups on agar surfaces, of Myxococcus xanthus requires type IV pili (TFP) and exopolysaccharides (EPS). Previous models proposed that this behavior, which only occurred within cell groups, requires cycles of TFP extension and retraction triggered by the close interaction of TFP with EPS. However, the curious observation that ...

Previous research has allowed developing and characterizing an expanded polystyrene waste (EPS) based insulation material that can be used to manufacture plates, providing job opportunities unemployed or vulnerable social groups. By working together with a local recycling cooperative, the production processes needed for their on scale suitable commercialization were determined. The goal of this...

The energy efficiency of buildings drives the replacement traditional construction materials with lightweight insulating materials. However, energy-efficient but combustible insulation might contribute to building’s fire load. Therefore, it is necessary analyse reaction-to-fire properties various provide a better understanding designing fire-safe structure. In this study, tests were carried out...

Recycling plastic waste has been one of the most significant challenges in recent decade. The reuse produced cellular plastics (i.e. EPS) within a conventional construction binder can contribute, simultaneously, to elimination and improving energy performances building envelopes. This work investigates recycling expanded polystyrene (EPS) cement-based matrix. aim is develop lightweight, energy-...
