01-12-2013· In particular the recycled plastic aggregate were characterised by values of thermal conductivity five times lower than the silica sand (0.28–0.30 W/mK and 1.3–1.4 W/mK respectively). Moreover the thermal insulating performance of the composite mortars containing plastic waste as aggregate is also strictly related to the porosity, which plays an important part in heat transfer.
Dry density was reduced by about 8% from reference concrete for 20% replacement of stone by recycled plastic. It can be concluded that the recycled plastic aggregates may be used up to 15%...
09-08-2017· Disposal of large quantity of plastic causes land, water and air pollution etc.., so a study is conducted to recycle the plastic in concrete. This work investigates about the replacement of natural aggregate with non-biodegradable plastic aggregate made up of mixed plastic waste in concrete.

Plastics have become an essential part of our modern lifestyle, and the global plastic production has increased immensely during the past 50years. This has contributed greatly to the production of plastic-related waste. Reuse of waste and recycled plastic materials in concrete mix as an environmenta …
Plastic is one of the world's most-used materials. Technically sophisticated, lightweight and cheap, plastics suit a broad spectrum of uses. The problem with plastic lies not in how it is used, which is generally harmless, but in end-of-life management of products made from it. Since 1950, close to half of all plastic has ended up in landfill or dumped in the wild, and only 9% of used ...
Thanks to its numerous applications and practical use, plastic is one of the world's most used materials. However, only 8% of the plastic used is coming from recycling, highlighting the bottlenecks in existing plastic recycling value chain and leading to environmental and resource concerns. In answer to end-of-life plastics concerns, Axens ...
Materials recycled in road construction include fly ash, silica fume, ground-granulated blast fur-nace slag, reclaimed asphalt pavement (RAP), and plastic wastes such as polyethylene terephthalate (PET), polystyrene (PS), polyvinyl chloride (PVC), ed polystyrene (FP),low-density polyethylene
plastic in concrete industry is considered as the most feasible application. Recycled plastic can be used as fine aggregate in concrete. However, it is the important to underline that reusing of waste is not yet - economically advantageous, due to the high costs of transport and its effect on the total costs. PLASTIC
conventional coarse aggregates by recycled plastic, the compressive strength of concrete increased by about 27.4% compared to the control concrete, while at a temperature of 400oC, the compressive strengths of normal aggregate concrete and recycled plastics concrete reduced by 33% and 75% respectively. Elzafraney et al. (2006)
26-10-2016· A novel aggregate (RPA) comprising recycled plastic was developed. The aggregate produced was lightweight, with a density ranging from 510 …
01-12-2013· a plastic aggregate (P), obtained from industrial waste, produced by the Company Vedelago Recycling Centre Ltd. (Treviso) through a process that provides a plasticization and densification by extrusion of the polymeric fraction of the waste ().In particular, the recycled plastic material, called R-POMIX "POLIMAR" is classified as secondary raw material and it is compliant with …
PET plastic waste is recycled by heating to a boiling point of approximately 300°C. There are five variations of concrete mixtures, defined the percentage of PET artificial aggregate to the total coarse aggregate, by 0, 25, 50, 75 and . Tests carried out on fresh concrete mixtures are slump, bleeding, and segregation tests.

07-11-2016· This paper presents the results of seismic tests on the recycled aggregate concrete filled steel tube (RCFS) and recycled aggregate concrete filled glass fiber reinforced plastic (GFRP) tube (RCFF) columns. The objective of this study is to evaluate the seismic behavior of steel/ GFRP tube in-filled recycled aggregate concrete (RAC) columns.
15-09-2016· Recycled aggregates actually show a relatively high rate of absorption during the first hour after mixing, i.e. before the development of plastic shrinkage. A stress/strength approach based on experimentally assessed parameters was used to compare the cracking sensitivity of different concretes with recycled aggregates.
