  2. 1. 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

  4. 2. 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.

  5. 3. Concrete Bridges : Improved Load Capacity

    Author : Jonny Nilimaa; Terje Kanstad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. READ MORE

  6. 4. Reducing Radon Gas Emissions in Concrete

    Author : Magnus Döse; Johan Silfwerbrand; Franz Josef Maringer; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon gas; emissions; health; concrete; building materials; ionizing radiation; Betongbyggnad; Concrete Structures;

    Abstract : Several compulsory regulations and recommendations regarding ionising radiation for building products have been introduced in recent years. Furthermore, industry-affiliated aggregate and concrete companies strive to implement environmental goals that should be fulfilled regarding building materials. READ MORE

  7. 5. Material Properties of Bulk Hydrophobic Concrete in a Nordic Environment

    Author : Patrick Rogers; Johan Silfwerbrand; Tang Luping; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alkyl alkoxysilane; capillary suction; chloride ingress; concrete; hydrophobic agents; triacylglycerides; Betongbyggnad; Concrete Structures;

    Abstract : Concrete in its unaltered form allows the mass transfer of fluids into and out of its microstructure. These fluids can contain detrimental solutes which change the chemistry of the cement paste and/or the corrosion properties of the reinforcement bars, most noticeably hydrogen carbonates (HCO3-), oxygen (O2) and chloride ions (Cl-).
