An inter- and transdisciplinary concept has been developed, focusing on the scaling of industrial circular construction using innovative compacted mineral mixtures (CMM) derived from various soil types (sand, silt, clay) and recycled mineral waste. The concept aims to accelerate the systemic transformation of the construction industry towards carbon neutrality by promoting the large-scale adoption and automation of CMM-based construction materials, which incorporate natural mineral components and recycled aggregates or industrial by-products. In close collaboration with international and domestic stakeholders in the construction sector, the concept explores the integration of various CMM-based construction methods for producing wall elements in conventional building construction. Leveraging a digital urban mining platform, the concept aims to standardize the production process and enable mass-scale production. The ultimate goal is to fully harness the potential of automated CMM-based wall elements as a fast, competitive, emission-free, and recyclable alternative to traditional masonry and concrete construction techniques. To achieve this objective, the concept draws upon the latest advances in soil mechanics, rheology, and automation and incorporates open-source digital platform technologies to enhance data accessibility, processing, and knowledge acquisition. This will bolster confidence in CMM-based technologies and facilitate their widespread adoption. The extraordinary transfer potential of this approach necessitates both basic and applied research. As such, the proposed transformative, inter- and transdisciplinary concept will be conducted and synthesized using a comprehensive, holistic, and transfer-oriented methodology.

The Industrialisation of Sustainable Construction: A Transdisciplinary Approach to the Large-Scale Introduction of Compacted Mineral Mixtures (CMMs) into Building Construction

Increasing demand for sustainable, resilient, and low-carbon construction materials has highlighted the potential of Compacted Mineral Mixtures (CMMs), which are formulated from various soil types (sand, silt, clay) and recycled mineral waste. This paper presents a comprehensive inter- and transdisciplinary research concept that aims to industrialise and scale up the adoption of CMM-based construction materials and methods, thereby accelerating the construction industry’s systemic transition towards carbon neutrality. By drawing upon the latest advances in soil mechanics, rheology, and automation, we propose the development of a robust material properties database to inform the design and application of CMM-based materials, taking into account their complex, time-dependent behaviour. Advanced soil mechanical tests would be utilised to ensure optimal performance under various loading and ageing conditions. This research has also recognised the importance of context-specific strategies for CMM adoption. We have explored the implications and limitations of implementing the proposed framework in developing countries, particularly where resources may be constrained. We aim to shed light on socio-economic and regulatory aspects that could influence the adoption of these sustainable construction methods. The proposed concept explores how the automated production of CMM-based wall elements can become a fast, competitive, emission-free, and recyclable alternative to traditional masonry and concrete construction techniques. We advocate for the integration of open-source digital platform technologies to enhance data accessibility, processing, and knowledge acquisition; to boost confidence in CMM-based technologies; and to catalyse their widespread adoption. We believe that the transformative potential of this research necessitates a blend of basic and applied investigation using a comprehensive, holistic, and transfer-oriented methodology. Thus, this paper serves to highlight the viability and multiple benefits of CMMs in construction, emphasising their pivotal role in advancing sustainable development and resilience in the built environment.

1900-luvun alussa historioitsijat Martti Kovero ja J. R. Danielson-Kalmari kirjoittivat Savon ja Karjalan läänin viranomaisten vakavista väärinkäytöksistä 1800-luvun taitteessa. Läänin ylimmät virkamiehet olivat keränneet isojako- ja verollepanotoimitusten varjolla asukkailta kohtuuttoman suuria maksuja sekä kantaneet verotuloja itselleen. Seudun hallinto oli joutunut alennustilaan ja talouselämä vaikeuksiin. Sittemmin historian professori Matti Klinge on pitänyt edellä mainittuja kuvauksia liioiteltuina. Klingen mukaan alueen väärinkäytökset olivat oire yhteiskuntaa modernisoivien maanomistus- ja verouudistusten läpiviennin haasteista kaskiviljelysalueilla. Artikkeli analysoi oikeudenkäyntiaineistojen avulla tämän korruptioskandaalin taustoja ja selvitysprosessin etenemistä. Savon ja Karjalan läänin uudeksi maaherraksi vuonna 1803 nimitetty Olof Wibelius sai tehtäväkseen siivota läänin hallinto. Wibelius onnistui tehtävässään, vaikka väärinkäytöksiä selvittäneet syyttäjät, tuomarit ja itse maaherrakin joutuivat jatkuvan häirinnän kohteiksi. Syynä olivat omalaatuiset lojaaliussuhteet, joita erilaiset laittomat sopimukset olivat luoneet vanhan virkakunnan ja asukkaiden välille. Vaasan hovioikeus tuomitsi keväällä 1806 edellisen maaherran ja lääninhallituksen virastojen johtajat ankariin rangaistuksiin. Artikkeli luo aiempaa kokonaisvaltaisemman kuvan kustavilaisen ajan oikeuslaitoksen keinoista ja mahdollisuuksista puuttua läänin korkeiden virkamiesten vakaviin väärinkäytöksiin. Mittavan rikosvyyhden analyysi mahdollistaa kokonaistulkinnan siitä, kuinka aluehallintoon oli muodostunut virkamiesjohtoinen varjoyhteiskunta. Se oli pystynyt toimimaan vuosien ajan keskitetyn valtiovallan ulkopuolella ja noudattanut omia, lakiin perustumattomia sääntöjään. Tämä oli yksi seuraus keskushallinnon komentosuhteiden hämärtymisestä ja viranomaisten toiminnan keskitetyn valvonnan heikkenemisestä kustavilaisella ajalla.
