  4. 2. Recycling of concrete in new structural concrete

    Author : Madumita Sadagopan; Andrzej Cwirzen; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete recycling; sustainability; closed-loop recycling; recycled aggregates; compressive strength; workability mechanical pre-processing; secondary cementitious materials; green concrete; climate-optimized concrete; Resource Recovery; Resursåtervinning;

    Abstract : Concrete waste as crushed concrete aggregates (CCA) in structural concrete gives a new purpose and prolongs the technical life of the reference concrete accomplishing closed loop recycling. This research investigates CCA as aggregate replacement in an industrial reference concrete recipe as fine aggregate fractions and overall aggregate replacement. READ MORE

  5. 3. Applied Modeling of Moisture Phenomena in Concrete

    Author : Marcin Stelmarczyk; Andrzej Cwirzen; Hans Hedlund; Klaas van Breugel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; Modeling degree of hydration; Modeling chemically bounded water; Modeling moisture sorption; Modeling moisture transport; Hysteresis; Byggmaterial; Building Materials;

    Abstract : This thesis contains new and improved calculation models, based on applied research merging numerical modeling and material research, in the areas of hydration and chemical binding of water, sorption of moisture and transport of moisture in concrete. The proposed model for hydration and chemical binding of water is based on general kinetics modeling and calculates degree of hydration directly, without using of equivalent time of maturity.

  6. 4. High-performance and self-compacting concrete in house building. Field tests and theoretical studies of possibilities and difficulties

    Author : Markus Peterson; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-storey residential buildings; Structural frames; SCC; Self-compacting concrete; High-performanceconcrete; HPC; Concrete; Building materials; Cast in-situ concrete;

    Abstract : Cast in-situ concrete is the most frequently used materials technology worldwide within production of structural frames in multi-storey residential buildings. In Sweden, this technology dominates the market but is challenged by other competitive production methods. READ MORE

  7. 5. Self-Healing Concrete

    Author : Magdalena Rajczakowska; Andrzej Cwirzen; Karin Habermehl-Cwirzen; Hans Hedlund; Erik Schlangen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cementitious materials; self-healing; exposure; fly ash; calcite; C-S-H; cracking; Byggmaterial; Building Materials;

    Abstract : Concrete is a brittle material prone to cracking due to its low tensile strength. Crack repairs are not only expensive and time-consuming but also increase the carbon footprint. Designing a novel concrete material possessing the ability to self-repair cracks would enhance its sustainability. READ MORE
