  1. 1. 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

  4. 3. Characterisation and Consolidation of Historical Lime Mortars in Cultural Heritage Buildings and Associated Structures in East Africa

    Författare :Athuman M. K. Ngoma; Jonas Holmgren; Jan Erik Lindqvist; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; East Africa; Stone Town; historical building; mortar; deterioration; consolidation; calcium hydroxide solution; Building engineering; Byggnadsteknik;

    Sammanfattning : For the period of several centuries, the influence of several distinct cultures produced rich and diverse cultural heritage that we see today in East Africa countries. The most tangible remains of these heritages are stone built buildings and structures including, palaces, mosques, residential houses and tombs. LÄS MER

  5. 4. Chloride transport and reinforcement corrosion in the vicinity of the transition zone between substrate and repair concrete

    Författare :Pål Skoglund; Jonas Holmgren; Erik Nordström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Sammanfattning : One of the major degradation problems in concrete structures is chloride initiated reinforcement corrosion resulting in cracked, spalled and delaminated concrete. Thesedamages are repaired for large amounts of money and because of high repair costs it is important to perform durable repairs. LÄS MER
