  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; Lund University.; Lunds universitet.; [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; Betong & Berg.; [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. Traditional lime mortar and plaster Reconstruction with emphasis on durability

    University dissertation from Göteborg : Chalmers Tekniska Högskola

    Author : Kristin Balksten; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Conservation HGO ; Kulturvård HGO ; lime plaster; lime mortar; masonry; craftsmanship; pore structure; frost resistance; historic mortar;

    Abstract : Lime mortar and plaster have been investigated with the aim to improve the knowledge on how to make them as durable as before the cement technology was developed. The background was the durability problems experienced for newly produced lime plaster on the medieval churches on the island of Gotland, Sweden. READ MORE

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

    University dissertation from Göteborg : Chalmers Tekniska Högskola

    Author : Nilla Olsson; Lund University.; Lunds universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cement; Bruk; Betong; Jontransport; Fukttransport; Sorptionsisoterm; Tillsatsmaterial; Kiselstoft; Masugnsslagg; Ciment; Mortier; Béton; Transport ionique; Transport d humidité; Sorption de vapeur d eau; Additions minérales; Fumée de silice; Laitier de haut fourneau granulé moulu; Cement; Mortar; Concrete; Ion transport; moisture transport; Water vapor sorption; Supplementary cementitious materials SCMs ; Silica fume; Ground granulated blast furnace slag;

    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
