Use of recycled mixed aggregates in floor blocks manufacturing

Structural and thermal retrofitting of masonry walls: An integrated cost-analysis approach for the Italian context

“…Actually, masonry buildings in Europe built before 1990 often require retrofitting interventions aimed at improving structural and thermal performances, to fulfill current standards requirements. In addition, the sustainability awareness of buildings life cycle has grown in the last years and re-use of construction demolition waste is becoming a common solution to reduce the construction environmental impact [1][2][3][4]. It is then necessary to design and to retrofit, taking into account how much energy will be spent for the refurbishment and how much will change the thermal and structural performance of the construction.…”

Use of Recycled Aggregates From Demolition Wastes in Concrete: Acoustic Properties

“…The samples prepared with ceramic aggregates exhibits the lowest porosity among those which allowed density measurement. This fact is quite common, due to the high porosity measured in ceramic aggregates in previous works [8], [15]. The elements prepared with arlite, EVA and rubber showed a density lower than water, and this did not allow the proper determination of the density.…”

Construction and demolition waste as recycled aggregate for environmentally friendly concrete paving

“…Nowadays, CDW has been successfully recycled as base and sub-base of road construction (Poon and Chan 2006a;Tavakoli Mehrjardi et al 2020;Zhang et al 2021), paving projects (Arulrajah et al 2014;Gedik 2020;Özalp et al 2016), footpaths projects (Arulrajah et al 2013;Arulrajah et al 2016;Pourkhorshidi et al 2020) and pipe-bedding projects (Arulrajah et al 2017;Rahman et al 2014;Taha et al 2002). Nevertheless, it is still necessary to develop new applications for the manufacture of new products, by developing originals processes, by seeking and finding new markets in order to absorb and reduce the vast volume of CDW worldwide production, and furthermore, to comply with the objective established by EU (Commission Consequently, previous studies using RA obtained from CDW have developed new applications mainly focused on the use of these sorts of materials as NA replacement in concrete production (Falek et al 2017;Favaretto et al 2017;Ibrahim et al 2020;Idagu 2017;Lau et al 2014;Martín-Morales et al 2011;Rao et al 2007;Robalo et al 2021;Tabsh and Abdelfatah 2009;Sharmal and Singla 2014;Silva et al 2014;Yang et al 2011) and concrete materials manufacturing, i.e., concrete bricks (Contreras et al 2016;Devi et al 2020;Poon et al 2002;Rodríguez et al 2016;Sadek et al 2013;Silva et al 2019) and concrete block (Kumar et al 2020;Leiva et al 2013;López et al 2018;Poon et al 2002Poon et al , 2009…”
