Collection description
The environmental emergency and climate change have become a highly topical issue that cannot be ignored. The indiscriminate use of resources, energy consumption and designs lacking in attention to sustainability, have led to a redefinition of the criteria and policies needed to guarantee the protection of the environment and standards of comfort and well-being. The construction industry, which accounts for one third of the European Union's total energy consumption, is part of this scenario, where demolition activities play an important role in the final balance in terms of waste materials produced. In order to protect raw materials and the environment, reduce emissions and waste, and improve the quality of life, it is necessary to rethink sustainable design, introducing recycled materials with innovative solutions. This research work introduces a new type of construction materials obtained from construction and demolition waste to be introduced on the market in a circular economy perspective. In order to verify the potential of reused waste materials in a geopolymer mixture, several experiments were conducted on samples produced at 60 degrees for 3 days from construction and demolition waste. The results show that the materials produced have good physical and mechanical characteristics comparable to those produced with traditional technologies. Based on these results, it can be conclude that geopolymer-based materials represent an important alternative to current binder production systems due to their potential to reduce emissions and energy consumption, thanks to low production temperatures, while respecting the properties of the mixtures and thus ensuring the use of compatible materials to be applied also in the field of rehabilitation of the existing heritage.
