  1. 16. Water and alkali salts in the hydrating and hardened green cement-based materials: Hydration process, moisture content and transport

    Författare :Liming Huang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

    Sammanfattning : Reducing CO2 emissions in the production of cementitious binder is the most effective way to decrease the environmental impact of the construction industry, so a large amount of supplementary cementitious materials (SCMs) has been used in the green concrete. Both the SCMs and alkali salts in binders influence the hydration process and the structure in hardened cement-based materials. LÄS MER

  3. 17. Approaching Strategic Sustainable Materials Management

    Författare :Pia Lindahl; Blekinge Tekniska Högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material selection; Strategic sustainable development; Sustainable materials management;

    Sammanfattning : Society’s sustainability challenges relatedto materials management have been an area of concern for policymakers, industry and the public for decades. However, if those challenges are managed in a strategic way, they are not only aproblem, but could also bring in new opportunity for companies and other organizations to improve their competitiveness through developingproduct-service systems that promote sustainable development of society.

    Sammanfattning : There is a general consensus that education is crucial for achieving sustainable development. Education for sustainable development aims to foster citizens capable of participating independently and actively in creating a sustainable future. LÄS MER

  5. 19. Microcapsules for Functionalization of Fibrous Materials: From Formulation Development to Long-term Microbial Infection Control

    Författare :Viktor Eriksson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Controlled release; Antimicrobial; Microencapsulation;

    Sammanfattning : In response to growing concerns regarding the impact of antimicrobial agents on the environment and public health, a more sustainable approach to their use in products is needed. The problem originates from rapid and uncontrolled release, leading to difficulties in maintaining long-term efficacy. LÄS MER

  7. 20. Deformation mechanisms and load distribution in multi-phase engineering materials

    Författare :Nitesh Raj Jaladurgam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Deformation mechanisms; Electron microscopy; Eutectic high entropy alloys; Load distribution; Superalloys; In-situ neutron diffraction;

    Sammanfattning : While the transition to carbon neutral technologies is still in progress, it is vital to reduce the environmental impact of existing processes. The efficiency of combustion processes for e.g. power generation and aviation can be greatly improved by increasing the operating temperature. LÄS MER
