Scientists from the Kyiv National University of Construction and Architecture (KNUCA), together with partners, have begun implementing an international project to create new concrete mixtures using waste, in particular, destroyed structures, for construction using 3D printing and traditional methods, according to the KNUCA press service.
The release states that as part of the project “Development of new approaches and construction materials for the restoration of Ukraine’s damaged infrastructure with consideration for environmental sustainability,” researchers are developing a concrete mixture with the addition of materials resulting from the destruction of buildings and other industrial and agricultural waste.
The restoration of housing in Ukraine requires the introduction of universal rapid construction technologies that allow for the construction of sustainable and affordable buildings even in conditions of limited resources. Due to the war, many buildings in Ukraine have been destroyed. The remains of concrete structures can be effectively recycled and used for the construction of new housing. Compared to traditional construction methods, 3D printing of buildings can ensure faster construction rates, significantly less use of human resources, and savings in materials and energy.
The project is co-funded by the US Office of Naval Research and the US National Science Foundation (NSF). The research is being conducted as part of the multilateral partnership initiative ” International Multilateral Partnership for Ensuring the Sustainability of the Education and Science System in Ukraine (IMPRESS-U),” initiated by the Office of International Science and Engineering (OISE) of the US National Science Foundation with the involvement of researchers from Stony Brook University in the US and the Jan and Jędrzej Śniadecki University of Technology in Bydgoszcz, Poland.
The project will last two years. At KNUBA, the implementation of this project is entrusted to teachers, graduate students, and students of the Faculty of Construction and Technology, in particular, the Department of Building Materials and the Department of Building Structures and Products Technology.
