Summer in DeConcrete format: conferences, training programmes and new publications
21.09.2021

Despite the vacation period, the experts of the international project DeConcrete: Eco-Efficient Arctic Technologies Cooperation continued with their agenda.

On July 13, project expert Priya Perumal (University of Oulu, Finland) presented her research on improving the quality of recycled concrete-based aggregate to the Young Concrete Researchers, Engineers and Technologist Symposium (YCRETS). An international event, YCRETS discussed a wide range of topics, including durability of new-generation constructional materials, monitoring and repair of reinforced concrete structures, and challenges of structural design and management.

Kalle Kursula (project expert, University of Oulu) received comments on his first article “Granulation and carbonation of ready mix concrete fines as lightweight aggregate”. This involves utilizing the produced granules as replacement for commercial lightweight aggregate.

17 July a «Comprehensive Summary of Available Legislation and Practices in Demolition and Construction & Demolition Waste Management in the Arctic Region» was published in Journal of Nordic Concrete Research https://www.sciendo.com/article/10.2478/ncr-2021-0009. The Nordic Concrete Research (NCR) (bi-annual publications) is since 1982 published by the Nordic Concrete Federation.

Earlier in July, the team of NArFU Higher School of Engineering’s Department of Composite Materials and Environmental Engineering have prepared the article titled The Integral Quality Performance of Recycled Concrete that discusses the criteria for evaluating concrete scrap to identify its optimal applications as a binder component, coarse or fine-grained aggregate, or fine dispersion filler. The proposed criteria have an important practical value for the industrial enterprises intending to use concrete scrap in the most efficient way. For the purpose of scientific experimenting, concrete was sampled from a building under demolition in the village of Obozersky during the project team’s trip in September 2020. The subsequent research made use of the unique facility called “Physical chemistry of nanodisperse systems surfaces”, a part of which was purchased as part of the project.

July 29 witnessed NArFU enter into a cooperation agreement with Tomsk State University of Architecture and Building (TSUAB), preceded by the project experts’ trip to TSUAB earlier in April. The team of TSUAB departments of constructional materials, technologies, reinforced concrete and stone structures act as external reviewers of the analytical reports prepared by the project partners in Norway on the demolition and separation methods.

DeConcrete’s outcomes – research materials, experimentally obtained data, recommendations, analytical materials – have been used in the development of the complementary advanced training programme “Concrete Recycling: Environmentally Efficient Arctic Technologies”. Designed to equip its target audience with the competencies for better effectiveness in the development of eco-efficient technologies for the production and recycling of building materials in the Arctic zone, the programme expects its first enrollment in the spring of 2022.

Notably, the year 2022 will see the updates to scientific major Constructional Materials and Products. One update relates to the newly introduced line of research called Development of Methods for Recycling and Reuse of the Materials from Building Demolition.

The training programmes that rely on the research conducted by DeConcrete project, which is funded by Cross-Border Cooperation Programme KOLARCTIC, are being developed also by the project partners in Norway and Finland.
