  2. 1. Systems Analysis for Eco-Industrial Development : Applied on Cement and Biogas Production Systems

    Author : Roozbeh Feiz; Mats Eklund; Jonas Ammenberg; Olli Salmi; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial ecology; eco-industrial development; multi-criteria analysis; life-cycle assessment; MCA; LCA; uncertainty management; systems analysis; industrial symbiosis; cement; biogas; cement production; biogas solutions;

    Abstract : Our industrial systems are not sustainable—a major challenge which demands several types of responses. Eco-industrial development can be seen as such a response, with the goal to establish industrial systems that are both ecological and economical. Industrial Ecology is another closely related response. READ MORE

  4. 2. Interaction of water with supplementary cementitious materials: Hydration mechanism, microstructure and moisture transport

    Author : Liming Huang; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydration; moisture transport; Supplementary cementitious materials; electrical conductivity; formation factor; durability; microstructure;

    Abstract : Supplementary cementitious materials (SCMs) offer a sustainable solution to reduce carbon emissions from the production of cement and concrete. This dissertation explores the impact of SCMs and the related additives on the hydration process of cementitious materials, which can affect their microstructure and transport properties. READ MORE

  5. 3. Experimental studies of sorption and transport of moisture in cement based materials with supplementary cementitious materials

    Author : Mahsa Saeidpour; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Concrete; Moisture transport; Hysteresis; Supplementary cementitious materials; Water vapor sorption; Sorption isotherms; Anomalous sorption;

    Abstract : Most deterioration processes in cement based materials are closely related to moisture sorption and moisture transport properties. Therefore, it is important to study these properties, both theoretically and practically. This work is an experimental investigation in this field. READ MORE

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

    Author : Liming Huang; Chalmers tekniska högskola; []
    Keywords : 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;

    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

  7. 5. Early Hydration of Portland Cement

    Author : Rikard Ylmén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SEM; freeze-drying; cement; calorimetry; nano-silica; carbonation; hydration; FTIR; infrared spectroscopy;

    Abstract : The production of cement is responsible forapproximately 7 % of the total CO2 emissions caused by man. To compensate for high energyconsumption and CO2 emission, thus making the utilization of concrete more sustainable,several strategies can be used. READ MORE
