  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. Portland Cement Clinker - Composition and Hydration

    Author : Anna Emanuelson; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; mineralisation; hydration; polymorphism; substitutions; ferrite; aluminate; belite; alite; Portland cement clinker; phase analysis; Oorganisk kemi; Material technology; Materiallära; materialteknik;

    Abstract : The crystal structures of the main Portland cement clinker phases are reviewed and two anion centered models of Ca3SiO5 and Ca2SiO4 are presented. The effects of minor elements on the clinkering process, and on the qualitative and quantitative phase compositions of Portland cement clinker are discussed. READ MORE
