“…Ozbakkaloglu and Gu [1] studied short-term mechanical properties of concrete with recycled polypropylene coarse aggregates and stated that recycled plastic aggregate concrete brings lower mechanical resistance compared to reference concrete mixture. In other studies, PP was used in mixture with other types of plastics or with another waste as fly ash or wood [3,5,9,10,11]. To date no study has been reported on the use of waste expanded polypropylene (EPP) as aggregate.…”

Recycled plastic aggregate can be used as an alternative material to produce lightweight concrete with low environmental impact. Polypropylene is one of the least recycled post-consumer plastics. In the present study we focused at waste expanded polypropylene (EPP) aggregate that is used for partial replacement of natural aggregate to produce lightweight cementbased composites. Coagulated silica was used as admixture for improvement of dispersion of EPP particles in the cementbased matrix. At first, natural and EPP aggregates were examined. Coagulated silica was characterized by SEM, EDS, XRF, particles size distribution and pozzolanic activity. Analysis of the microstructure of lightweight concrete was performed using an optical microscope, SEM imaging and EDS. For the developed lightweight concrete, basic physical, mechanical and hygric properties were examined. Specific attention was paid to thermal properties. The results show, using of plastic waste aggregate led to a sufficient mechanical resistance, whereas the thermal insulation performance of the developed concrete was markedly improved. Composite with incorporated PP waste aggregates was found to be prospective material for nonstructural applications in building industry, which allows the development of buildings with optimum energy performance as well as reduce the growing environmental impact of waste polymers and saving the natural aggregates.

“…Among the several potential applications of mechanically recycled FRP waste in new composite materials, a significant amount of research work has been carried out on Portland cement concrete in which the effect of GFRP recyclates, and more rarely CFRP recyclates, has been analyzed and assessed either as reinforcement, aggregate or filler replacement [27][28][29][30][31][32][33][34][35][36][37][38][39][40][41]. In the analyzed studies, a wide-range of replacement amounts was assessed: between 1% up to 20% in weight of total aggregates (after conversion of volume content to weight content).…”

Worldwide volume production and consumption of engineered composite materials, namely fiber reinforced polymers (FRP), have increased in the last decades, mostly in the construction, automobile, aeronautic and wind energy sectors. This rising production and consumption have also led to an increasing amount of FRP waste, either end-of-life (EoL) products or manufacturing rejects. Taking into account the actual and impending EU framework on waste management, in which clear targets are set with concrete measures to ensure effective implementation, landfill and incineration will be progressively unavailable as traditional end-routes for this kind of waste. Recycling techniques and end-use applications for the recyclates have been investigated over the past twenty years, but even so, more cost-effective and feasible market outlets for the recyclates should be identified that meet both the economic and the environmental points of view. This paper is aimed at enclosing and summarizing an update overview regarding all these issues: current legislation, recycling techniques and end-use applications for the recyclates. Additionally, as a case study, the assessment of the potential improvements that could be made on the eco-efficiency performance (sustainability) of a typical FRP composite materials' industry by recycling and re-engineering process approaches is also reported.

“…The mortar is an advantageous material to produce concrete, plaster and some wall materials. The obtained insulation materials, different from concrete, is sought for lightness and insulation properties [1]. Moreover, fireproofing is also a desirable feature in new types of building materials [2].…”

One of the best methods of waste recycling in the construction sector is to employ it in concrete or mortar preparation. In this study, recycled concrete aggregate and bottom ash were used as aggregates in the mortar. Additionaly, expanded perlite which is a material providing lightness, heat insulation and fire resistance, was also used as aggregate. Calcium aluminate cement was preferred as binder to improve fire resistance. Results were obtained and evaluated in terms of flexural and compressive strength, dry unit weight, water absorption, capillarity, thermal conductivity, thermal resistance and cost by following a Taguchi method to internal curing, cement quantity and aggregate ratio as parameters.
