In the European Union, demand for polyurethane is continually growing. 2017, estimated value of production was 700,400 Tn, which 27.3% taken to landfill, causes an environmental problem. this paper, behaviour various foams from waste different types industries will be analyzed with aim assessing their potential use in construction materials. To achieve this, wastes were chemically tested by means CHNS, TGA, and leaching tests. They microstructurally SEM. The processing parameters calculated...
Gypsum plasterboard that incorporates various combinations of polyurethane foam waste and polypropylene fibers in its matrix is studied. The prefabricated material was characterized a series standardized tests: bulk density, maximum breaking load under flexion stress, total water absorption, surface hardness, thermal properties, reaction to fire performance. Polypropylene were added the gypsum composites improve mechanical behavior loading. results indicate increased quantities polymer led...
In this paper, the LCA of two gypsum ceiling tiles is compared, first one a traditional tile and second new eco in which polyurethane foam waste has been incorporated. Both were made at largest factories Europe. The life cycle assessment considered from cradle to grave for corresponding production stages have defined. This includes extraction transportation raw materials, manufacturing process, client, use product end its useful life. results show that with better environmental performance...
The adoption of sustainable building policies and the society's increasing emphasis on sustainability underscore urgent need to evaluate environmental economic impact construction materials. This study examines effects incorporating polyurethane foam waste into gypsum-based ceiling tiles. It compares its performance eco-efficiency with conventional alternatives. Methodologically, Life Cycle Cost Analysis (LCCA) quantifies total life cycle costs, followed by Eco-Efficiency Assessment (EE),...
Demand of lithium is expected to increase drastically in coming years driven by the market penetration electric vehicles powered Li-ion batteries, which will require faster and more efficient Li extraction technologies than conventional ones (evaporation brines). The Electrochemical Ion Pumping Cell (EIPC) technology based on use Faradaic materials one most promising approaches. However, its relatively short lifespan prevents commercial deployment. Herein, a new EIPC concept semi-solid...
The properties and the behaviour of plaster mortars designed with Polyurethane Foam Waste (PFW) are studied in this investigation. A characterization mixtures is completed, accordance technical specifications European Norms. incorporation polyurethane waste foam can yield porous lighter mortars, better resistance to water-vapour permeability, although weaker mechanical strength higher levels absorbency. Nevertheless, suitable strengths were achieved, resulting a new material that compliant...
A modified forced silking procedure was developed to allow an accurate study of the tensile properties spider (Argiope trifasciata) silk, especially characterization variability forcibly silked fibers. The involves immobilization technique that does not require anesthetization spider, a mode collection allows immediate access any silk sample with minimum manipulation, and measure diameters fibers systematically. obtained by this show reproducible in terms force-displacement curves as well...
In the last few years, research in field of sustainability has experienced a significant increase interest between and other areas (inclusive education, active methodologies, society). Moreover, use mixed methods (quantitative qualitative) along with application data mining techniques, enables analysis information connection different studies. The objectives this paper were: (1) To establish results related to concepts sustainability, inclusive disability. (2) study key that are detected...
A series of mortars subjected to accelerated corrosion in a humid environment form the basis for this study. In particular, we studied behavior steel reinforcement bars that were embedded cement contained white ladle furnace slag (LFS) partial substitution fines and cement. The effects observed using computerized axial tomography scanning electron microscopy. Zones with fissures resulting from degree damage due passivation identified imaging analysis. Mortars without LFS behaved similar...
In accordance with the European politics of reducing amount polymers and plastics wastes, inclusion compounds such as roof wastes recycled reusable materials to replace variable amounts aggregates is interesting in production new construction due their physical chemical behaviour. Prefabricated mortar blocks have made Portland cement, sand, water grinded polyurethane based from automobile industry that different part or all aggregates. To try avoid mechanical resistance limitation use...
