Cement cobblestones lightened with industrial polymeric waste

for Economic Co-operation and Development [OECD], 2018), while annual waste generation in Europe is projected toincrease by 70% by 2050 (Kaza et al., 2018). For this reason, it is necessary a transition to a sustainable economic and productive system as part of the new industrial strategies. Recent studies estimate that applying circular economy principles has the potentialto improve the engineering procedures creating new qualified jobs. More than 80% of construction materials’ environmental impacts are determined at the design phase (European Commission, 2019). Many by products break down too fast and cannot be simply recycled, and many are made for single use only. Together with this condition, the management policies provide world-wide standards towards construction materials sustainability (Taurino, Bondioli, & Messori, 2023).With the aim of characterize this eco sustainable cobblestones, different durability tests have also been carried out as freeze-thawand crystallization salt, establishing the compressive strength before and after the test, confirming the suitable properties to be used in different – outdoor – environments.
