Thus, addition of PC plastic aggregates in cementitious materials seemed to provide good energy absorbing materials Toughness factors increase significantly with increasing volumeįraction of PC. Industrial scrap of PC was also employed as an aggregate to prepare concrete mixtures. Mortars made with different amounts of HIPS offers improved The authors concluded that the manufacture of Was employed by Wang and Meyer as a substitute for sand inĬement mortars. While several authors proposed the use of recycled plastic asĪggregate (RPA) or fiber for a concrete mixture, only aįew proposed the use of WEEEP in the same manner. Of both contaminants (heavy metals and polybrominated organicĬompounds) in the final recycled material. Materials, but it is particularly important to analyse the impact Thus, WEEEP could be used to develop novel recycled Under mechanical stress like bricks or aggregates for slab and concrete. Them adequate to produce constructive components that work Mechanical properties, such as high tensile and flexural modulusĪs well as slight impact strength. Raised over the toxicity of some BFR compounds and their riskįor the above, at present the plastic fraction of WEEE is treat by
Over the last decades, concerns have been The environment in areas far from the points of production or consumption. Typical loading of Br for flame retardantĪpplications ranges between 4 and 10%, depending on polymerįlame retardants, specially BFRs are persistent organic pollutants, which can be accumulated and detected in humans and With tetrabromobisphenol-A (TBBPA) and polybrominated diphenyl ethers (PBDEs), particularly decabromodiphenyl ether, being About 30–40 different BFRs compoundsĪre employed in electrical and electronic equipment (EEE) , Industry, and it is estimated that 40% of all flame retardant found
The main consumer of BFRs is the electronics WEEP, its toxicity makes an expanding negative impact on bothīFRs are one of the largest groups of flame retardants andĪccounted for about 20% of the global flame retardants consumption in 2011. Reuse of the plastic fraction WEEE (WEEEP), despite of their high (BFRs), and other hazardous compounds have limited the TheĮxistence of heavy metals, brominated flame retardants Polypropylene (PP) and ́0% of polycarbonate (PC). Mainly, the polymer distribution of WEEE is about a 30–35% of acrylonitrile butadiene styrene Over the last two decades, waste from electrical and electronicĮquipment (WEEE) became a significant pollution issue. We propose that the RPA with optimal physical and mechanical properties has great potential for use in Construction and Building Materials 230 (2020) 116977 We proved that the core-shell strategy, in whichĬement-activated charcoal shell was employed, produces a stabilization of the hazardous compounds.Ĭompression strength tests showed that RPAs could be used as replacement for sand in cement mortar.
(RPA) consisting of grinded WEEEP (core) and a mixture of cement and several additives such as a very fineĪggregate, clay or activated charcoal (shell) was obtained. In order to transform this waste into a useful and nonhazardous material, we developed a novel stabilization strategy. Important amount of brominated flame retardants and heavy metals, which suppose a risk to the health of There is known that the plastic fraction of waste electrical and electronic equipment (WEEEP) contains an Lopez y Cruz Roja Argentina, Córdoba, Argentina
