11. Industrial Fibre Concrete Floors : Experiences and Tests on Pile-Supported Slab
Sammanfattning : 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. LÄS MER
12. Design for 3D Concrete Printing : Optimisation Through Integrated Workflows
Sammanfattning : 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. LÄS MER
13. Fire Spalling of Concrete : Theoretical and Experimental Studies
Sammanfattning : 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. LÄS MER
14. Impregnation of concrete structures : transportation and fixation of moisture in water repellent treated concrete
Sammanfattning : 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. LÄS MER
