PhD defence on Alkali Silica Reaction in Concrete Slabs
Søren Gustenhoff Hansen from SDU Civil and Architectural Engineering will be defending his PHD Thesis: “Influence of Alkali-Silica Reaction on the Shear Capacity of Reinforced Concrete Slabs Without Shear Reinforcement” 3 July
Alkali-Silica Reaction (ASR) is a well-known deterioration mechanism that causes severe cracking in concrete structures. This cracking has raised serious concerns regarding the safety of ASR-damaged structures; particularly structures, which may be sensitive to shear failure.
Despite nearly eighty years of research on ASR and the fact that thousands of structures worldwide have the potential to develop ASR cracks, there exists no satisfactory method to assess the residual shear capacity of ASR-damaged slabs without shear reinforcement.
In his work, Søren presents an approach for determining the shear capacity of ASR-damaged slabs without shear reinforcement. The approach includes a shear model as well as recommendations and descriptions of how the relevant strength parameters can be determined by simple tests on samples taken from the structure.

The PHD Defense will take place Wednesday 3 July at 10:00 in room U170 (Building 44) at Campusvej 55, Odense.
