  1. 1. Early Hydration of Portland Cement

    Author : Rikard Ylmén; [2013]
    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

  2. 2. Portland Cement Clinker - Composition and Hydration

    University dissertation from Material Chemistry, P.O. Box 124, SE-221 00 Lund

    Author : Anna Emanuelson; Lunds universitet.; Lund University.; [2001]
    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

    Abstract : Mucus, an adherent hydrated layer covering the epithelium, is found in all internal tracts of the body and plays an important role in animal and human life. One of the essential functions of mucus is protection of tissues against dehydration. READ MORE

  5. 5. Acceptor-doped barium zirconate: Oxidation, hydration and space-charge formation

    University dissertation from Malmö University, Faculty of Health and Society

    Author : Anders Lindman; [2015]
