  2. 11. Industrial Fibre Concrete Floors : Experiences and Tests on Pile-Supported Slab

    Author : Jerry Hedebratt; Johan Silfwerbrand; Terje Kanstad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Pile supported floor slabs have often been designed solely in ultimate limit state ULS and then foremost with uniformly distributed loadings UDL. The investigation of serviceability limit state SLS has been of simpler nature, even according to the governing codes of practice. READ MORE

    Author : Jose Hernández Vargas; Johan Silfwerbrand; Helena Westerlind; Roberto Naboni; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D concrete printing; digital fabrication; concrete structures; additive manufacturing; robotic fabrication; design for manufacturing; structural optimisation; functionally graded concrete; topology optimisation.; 3D-betongutskrift; digital tillverkning; betongkonstruktioner; additiv tillverkning; robotstyrd tillverkning; design för tillverkning; strukturell optimering; funktionellt graderad betong; topologioptimering.; Betongbyggnad; Concrete Structures;

    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

  5. 13. Fire Spalling of Concrete : Theoretical and Experimental Studies

    Author : Robert Jansson; Johan Silfwerbrand; Ulrich Diedrichs; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Fire spalling of concrete is not a new phenomenon. To some degree there has always been a risk during rapid heating of concrete. Therefore, to a certain degree the effect of fire spalling is included in the bank of data from fire tests and fires on which our understanding of the fire resistance of concrete is based. READ MORE

  6. 14. Impregnation of concrete structures : transportation and fixation of moisture in water repellent treated concrete

    Author : Anders Johansson; Johan Silfwerbrand; Lars-Olof Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Abstract : Water repellent agents, today mainly consisting of alkylalkoxysilanes, are often used on concrete to prolong the service life of the structure. This is accomplished by protecting the reinforcement bars from chlorides or by changing the moisture content inside. READ MORE
