  2. 1. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials

    Author : Simon Magnusson; Sven Knutsson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Abstract : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. READ MORE

  5. 3. 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

    Abstract : The transition from conventional cast concrete to 3D Concrete Printing (3DCP) marks a paradigm shift by directly depositing fresh concrete layer upon layer according to a digital model without the need for a formwork. This technology offers the possibility of achieving innovative and complex geometries in an automated process. READ MORE

  7. 5. CONCRETE FORM[ing]WORK : Design, Fabrication, Simulation and Correlation of Parametrically Patterned Flexible Formwork and Concrete

    Author : Annie Locke Scherer; Oliver Tessmann; Jonas Runberger; Remo Pedreschi; KTH; []
    Keywords : HUMANIORA; HUMANITIES; concrete; flexible formwork; geometry; parametric patterning; craft; smocking; simulation; correlation; betong; flexibel formsättning; geometri; parametrisk mönsterkonstruktion; hantverk; smockning; simulering; korrelation; Architectural Technology; Arkitekturteknik;

    Abstract : Concrete is one of the most commonly used construction materials, yet industrial fabrication continues to default to established standards of planar formwork and uniform cross-sections for the sake of simplicity and predictability. The research conducted within Concrete Form[ing]work explored alternative methods of producing concrete formwork with a simple, technical re-imagination of material: exchanging the familiar, i.
