  1. 1. In-plane tension behaviour of masonry

    Författare :Miklos Molnar; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; restrained shrinkage; cracking; movement joints; Building construction; mortar joints; KstrMasonry; masonry; in-plane tension; Byggnadsteknik; murverk; sprickor; krympning; dilatationsfogar;

    Sammanfattning : The main purpose of the present work is to increase knowledge of in-plane tension behav-iour of masonry and develop a model able to describe the impact of parameters influencing cracking caused by restrained shrinkage. In the process the mechanism of load transfer between units and mortar joints is described. LÄS MER

  3. 2. Resistance of Clay Brick Masonry Façades to Wind-Driven Rain : Repointing of Eroded Mortar Joints

    Författare :Mohammad Kahangi; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; clay brick masonry façade; wind-driven rain; water absorption; water penetration; damp patches;

    Sammanfattning : Clay brick masonry façades are commonly used due to their high-performance durability. However, exposure to climate agents such as wind-driven rain (WDR), freeze-thaw cycles, and wind abrasion cause deterioration of masonry façades over time. LÄS MER

  4. 3. Kalkputs : porstrukturens betydelse för beständighet

    Författare :Kristin Balksten; Tor Broström; Britt-Marie Steenari; Jan-Erik Lindkvist; Chalmers; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kalkputs; kalkbruk; murning; putsning; hantverk; frostresistens; porstruktur; Conservation HGO ; Kulturvård HGO ;

    Sammanfattning : When restoring historic lime plaster it can be difficult to reach the required durability. Today newly made lime plaster can fall off due to frost damages after only a couple of winters. To understand and solve these problems, the subject has been studied from different perspectives.

  5. 4. Prestressed hybrids of AAC and HPC : The BCE (Block Composed Element) building system. A conceptual study

    Författare :Hamid Bagheri; Bo Göran Hellers; Jonas Holmgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Architecture and architectural conservation and restoration; Arkitektur och bebyggelsevård;

    Sammanfattning : There is an important potential for a development of a building system, if the present AACblock plants are completed with high performance concrete and pre-stressing technique. This can be done as a continuation of a present AAC production or in a site factory. Hybrid cooperation between AAC and concrete is not a new technology. LÄS MER
