As a result of the EU policy to strengthen the European Union by encouraging free trade of building products between member countries, product standards for almost hundred building product groups were created over the past 20 years. The product standard for EPS in Civil Engineering Applications (EN 14933) came into force in March 2009. This presentation will focus first on the results of the im...

An experimental program was implemented to investigate the shear transfer mechanism of carbon-fiber-reinforced polymer (CFRP) grids and expanded polystyrene (EPS) rigid foam insulation in three wythe precast concrete sandwich wall panels. The purpose research measure flow capacity observe failure mode(s) panels manufactured with a CFRP grid between wythes. Six were examined by push-out tests wh...

Activation of class F fly ash with the 10 M sodium hydroxide and sodium silicate and its geopolymeric products were analysed under quasi-isothermal mode of DSC, FTIR and TG/DTA techniques. Before adding in concrete, expanded polystyrene beads were prewetted with the styrenebutadienestyrene latex aimed at to improve their bonding with geopolymer. Lightweight mortars/concretes were made from geop...

Expanded polystyrene (EPS) geofoam is a lightweight compressible material that has been widely used in various civil engineering projects. One interesting application of EPS geotechnical to reduce the lateral earth pressure on rigid non-yielding retaining walls. The nature allows for shear strength backfill soil be mobilized, which leads reduction acting wall. In this study, finite element mode...

Abstract Shell folded footings have drawn the interest of researchers for decades as an alternative to typical flat isolated because can reduce needed amount reinforced concrete in addition enhancing overall geotechnical performance supporting soil medium. The main setback utilizing such is relatively complex geometry bottom cavity, which requires proper compaction used fill that cavity. Curren...

Information on the flows of specific polymers through anthroposphere forms basis any assessment environmental implications plastic. This work presents a dynamic probabilistic material flow analysis seven commodity thermoplastics: low-density polyethylene (LDPE), high-density (HDPE), polypropylene (PP), polystyrene (PS), expanded (EPS), polyvinylchloride (PVC), and terephthalate (PET). The exami...

Different plastics recovered from a local urban solid waste plant were collected before landfilling, separated, and classified by families, i.e. polyethylene (PE), polypropylene (PP), high impact expanded polystyrene (HIPS EPS, respectively), terephthalate (PET), polyvinyl chloride (PVC). A systematic pyrolysis study was carried out to compare the different behavior registered in each plastic t...
