  2. 1. 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.

  4. 2. Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation

    Author : Lars-Erik Harderup; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete slab; moisture; repair methods; ventilated foundation; drainage; numerical methods; grunder; grundplattor; platta på mark; betongplattor; fuktskador; reparationsmetoder; dränering; ventilerade konstruktioner; fukt; fukttransport; relativ fuktighet; temperatur; luftflöden; beräkningsmodeller; teori; fältundersökningar; mätresultat;

    Abstract : This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. READ MORE

  5. 3. Sliding stability re-assessment of concrete dams with bonded concrete-rock interfaces

    Author : Alexandra Krounis; Stefan Larsson; Fredrik Johansson; Ignacio Escuder Bueno; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; concrete dams; sliding stability; cohesion; shear strength; uncertainty; bond; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : The shear strength of the concrete-rock interface is an important parameter in sliding stability analyses of concrete dams founded on rock and depends, in addition to the normal stress state, on the bonding conditions of the interface; concrete-rock interfaces can be either unbonded, partially bonded or fully bonded.In the Swedish guidelines for dam safety all dam-foundation contacts are treated as unbonded.

  6. 4. Reliability-based evaluation of concrete dams

    Author : Marie Westberg; Avdelningen för Konstruktionsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spatial correlation; assessment; concrete dam; uplift; structural reliability analysis; existing structure;

    Abstract : Swedish concrete dams are designed and assessed based on deterministic design using safety factors. The combination of increasing age, new methods for calculation of design floods and increasing demands by society to ensure a high level of safety, has resulted in upgrading and rebuilding needs for dams.

  7. 5. Secondary Emissions from Concrete Floors with Bonded Flooring Materials - Effects of Alkaline Hydrolysis and Stored Decomposition Products

    Author : Anders Sjöberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOC; floorings; decomposition products; concrete; secondary emission; OCIC; moisture; IAQ; adhesive; building materials;

    Abstract : It has been demonstrated before that the presence of VOC lowers the quality of indoor air. There are also several indications that certain organic compounds in indoor air (OCIA) can give rise to sick building syndrome (SBS). READ MORE
