  2. 1. 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

  4. 2. Modeling the influence of magnesium from alternative raw materials on the chemistry of Portland cement clinker

    Author : Erik Viggh; Rainer Backman; Dan Boström; Bo Björkman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermodynamic modeling; process modeling; Portland cement; clinker; periclase; magnesium oxide; alite; Scheil calculation; solid solutions; Physical Chemistry; fysikalisk kemi;

    Abstract : The methods used in this thesis work were a combination of computational and modeling based laboratory experiments.Thermodynamic process modeling of the cement clinker process offers a tool for evaluating how changes in raw materials and process parameters affect the clinker quality.

  5. 3. Chloride transport and chloride threshold values : studies on concretes and mortars with Portland cement and limestone blended cement

    Author : Dimitrios Boubitsas; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Mortar; Concrete; Corrosion; Reinforcement; Chloride ions;

    Abstract : Reinforced concrete is one of the most widely used building materials and if it is properly designed and produced, it is an extremely durable material with a service life up to 100 years. However, under certain environmental conditions the service life of reinforced concrete structures is more limited. READ MORE
