  1. 1. Phase chemistry in process models for cement clinker and lime production

    Författare :Bodil Hökfors; Rainer Backman; Bo Björkman; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process modelling; phase chemistry; cement clinker; lime; sustainability; CO2; energy;

    Sammanfattning : The goal of the thesis is to evaluate if developed phase chemical process models for cement clinker and lime production processes are reliable to use as predictive tools in understanding the changes when introducing sustainability measures.The thesis describes the development of process simulation models in the application of sustainability measures as well as the evaluation of these models.

  4. 4. Traditional lime mortar and plaster : Reconstruction with emphasis on durability

    Författare :Kristin Balksten; Tor Broström; Britt-Marie Steenari; Thorborg Konow von; Chalmers Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime plaster; lime mortar; masonry; craftsmanship; pore structure; frost resistance; historic mortar; Conservation HGO ; Kulturvård HGO ;

    Sammanfattning : 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. LÄS MER

  5. 5. Strength variability in lime-cement columns and its effect on the reliability of embankments

    Författare :Mohammed Salim Al-Naqshabandy; Stefan Larsson; Lars Olsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; lime-cement; embankments;

    Sammanfattning : Ground improvement by deep mixing (DM) is a generic term used for a number of methods in which a binding agent, often lime and/or cement, is mechanically mixed with the soil to increase its engineering properties. The inherent variability with respect to the engineering properties of the improved soil is high due to the variations in geology and the complex mixing process. LÄS MER
