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

    Författare :Nilla Olsson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Experimental Study of De-icing Salt-frost Scaling in Concrete with Low-calcium Fly Ash or Slag : Influence of Drying and Carbonation, and Air Content

    Författare :Martin Strand; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Betong; Cement; Beständighet; Tösalt-frost avskalning; Tillsatsmaterial; Masugnsslagg; Flygaska; Concrete; Durability; De-icing salt-frost scaling; Cement based materials; Supplementary cementitious materials SCMs ; Ground granulated blast furnace slag; Low-calcium fly ash;

    Sammanfattning : In order to reduce the net climate impact of concrete production, it is necessary for the industry to undertake several actions. Among these is to include fly ash and slag as supplementary cementitious materials. Accordingly, this project has studied concrete containing low-calcium fly ash or ground-granulated blast-furnace slag. LÄS MER

  4. 3. Towards sustainability of environmental protection : recovery of nutrients from wastewater filtration and the washing of arsenic contaminated soils

    Författare :Lea Rastas Amofah; Helen French; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Conventional methods for wastewater treatment and remediation of the sites withcontaminated soils focus on protection of human health, receiving waters and theenvironment. Towards this end, these methods concentrate on the reduction or removal of polluting substances, and therefore, are not well suited for creating resources through the recovery of nutrients, energy and decontaminated soils.

  5. 4. Stabilisering av torv : olika faktorers inverkan på stabiliseringseffekten

    Författare :Kerstin Pousette; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Torvmarker är sättningskänsliga och ej lämpliga att bygga på. Om en väg eller järnväg ska byggas över torvmark måste åtgärder vidtas för att förstärka undergrunden. En metod som har börjat användas de senaste åren är masstabilisering, där ett stabiliseringsmedel blandas ner i torven för att öka dess hållfasthet. LÄS MER

  7. 5. Treatment conditions for the removal of contaminants from road runoff

    Författare :Magnus Hallberg; Gunno Renman; Jiri Marsalek; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolved matter; filter bed; particulate matter; sedimentation; suspended solids; Environmental engineering; Miljöteknik;

    Sammanfattning : The pollutant load in road runoff is related to traffic densities and road maintenance activities. Inurbanised areas treatment of road runoff is common and often considered necessary. The pollutantsare partitioned between the particulate and dissolved matter. However, the contaminantstend to have an affinity to the particulate material. LÄS MER
