  1. 1. Recycling of concrete in new structural concrete

    Author : Madumita Sadagopan; Andrzej Cwirzen; Högskolan i Borås; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; concrete recycling; sustainability; closed-loop recycling; recycled aggregates; compressive strength; workability mechanical pre-processing; secondary cementitious materials; green concrete; climate-optimized concrete; Resource Recovery; Resursåtervinning;

    Abstract : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. READ MORE

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

    Author : Liming Huang; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Formation factor; Electrical conductivity; Moisture transport; Pore structure; Sustainable cement-based materials; Hydration; Alkali salts; Supplementary cementitious materials;

    Abstract : 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. READ MORE

  3. 3. Rethinking lawns as prevalent elements of urban green spaces : exploring sustainable lawn alternatives in Chinese mega-cities from social-cultural and ecological perspectives

    Author : Fengping Yang; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : The lawn is one of the most visible elements of urban green spaces and Western landscape styles. China has seen a dramatic increase in planted lawn areas. READ MORE

  4. 4. Sound in landscape architecture : a soundscape approach to noise

    Author : Gunnar Cerwén; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []

    Abstract : Landscape planning and design involve decisions that have far-reaching effects, positive and negative, on the soundscape. However, landscape architecture and related disciplines have not fully recognised the possibilities of considering sound issues in design projects. READ MORE

  5. 5. Improving the Sustainability Performance of Building Materials: An Approach from Life Cycle Thinking

    Author : Jun Kono; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; sustainable product development; LCA; Social Life Cycle Assessment; sustainable building; Life cycle assessment;

    Abstract : The construction industry is expected to play a vital role in meeting the global societal challenge of ensuring sustainable development. Due to the increasing importance of the embodied impact of materials, this thesis investigates how the sustainability performance of building materials can be improved. READ MORE
