  1. 1. Moisture permeability of mature concrete, cement mortar and cement paste

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Göran Hedenblad; [1993]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture transport; cement paste; moisture permeability; concrete; moisture flow; cement mortar;

    Abstract : Moisture permeability tests were performed on specimens of concrete, cement mortar and cement paste with the bottom side in water or in moist air and the upper side in a relative humidity of 33 %. The distribution of the relative humidity within the specimen was measured, at stationary conditions, as well as the amount of water which pass through the specimen. READ MORE

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

    University dissertation from Lund : Division of Building Materials, Lund University

    Author : Dimitrios Boubitsas; [2016]
    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

  4. 4. Hydration, pore structure, and related moisture properties of fly ash blended cement-based materials : Experimental methods and laboratory measurements

    University dissertation from Department of Building and Environmental Technology, Lund University

    Author : Oskar Linderoth; [2020-09-01]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Murbruk; Betong; Hydratation; Porstruktur; Sorption; Fukttransport; Mineraliska tillsatsmaterial; Flygaska; Cement; Mortar; Concrete; Hydration; Pore structure; Water vapour sorption; Moisture transport; Supplementary cementitious materials; Fly ash;

    Abstract : Cement-based materials, such as mortar and concrete, are the most employed construction materials in the world. Cement is an important component; it reacts with water to form a glue, called cement paste, which causes the material to harden. Today, cement production accounts for a significant portion of the world’s annual carbon dioxide emissions. READ MORE

  5. 5. Experimental studies of ion transport in cementitious materials under partially saturated conditions

    University dissertation from Department of Building and Environmental Technology, Lund University

    Abstract : Cement production is responsible for a significant portion of manmade CO2 emissions. This motivates the development of cementitious binders with a lower carbon footprint. Considering the emissions in a longer perspective, the durability of concrete structures is absolutely essential. READ MORE
