  5. 8. Models for analysis of young cast and sprayed concrete subjected to impact-type loads

    Author : Lamis Ahmed; Anders Ansell; Richard Malm; Lennart Elfgren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Young concrete · Shotcrete · Rock · Impact-type vibration · Finite element method · Fracture mechanics model · Crack width;

    Abstract : The strive for a time-efficient construction process naturally put focus on the possibility of reducing the time of waiting between stages of construction, thereby minimizing the construction cost. If recently placed concrete, cast or sprayed, is exposed to impact vibrations at an early age while still in the process of hardening, damage that threatens the function of the hard concrete may occur.

  6. 9. Development of prefabricated timber-concrete composite floors

    Author : Elzbieta Lukaszewska; Hans-Joachim Blass; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : Timber-concrete composite structures were originally developed for bridges and upgrading of existing timber floors, but finds today new applications in multi-storey buildings. Most of the research performed to date has been focused on systems where "wet" concrete is cast on top of timber beams with mounted connectors. READ MORE

  7. 10. Service life of repaired concrete bridge decks

    Author : Johatan Paulsson-Tralla; KTH; []
    Keywords : ;

    Abstract : Pre-mature deterioration of reinforced concrete causesproblems world-wide and the search for reliable cost effectiveand environmental friendly repairs is intense. The service lifeof the repaired structure is important in order to establishthe annual cost and environmental impact for differentalternatives. READ MORE
