Shear Behaviour of Concrete affected by Alkali-Aggregate Reaction

The first part of this thesis project consist in a study of the structural behavior, mainly focusing on shear resistance, of concrete elements affected by alkali-aggregate reaction (AAR), an internal swelling reaction. Especially in the presence of moisture, this reaction causes the concrete to expand and form internal cracks. This expansion and formation of cracks is generally associated with a decrease in the mechanical properties of the concrete material. Shear issues of affected concrete is one critical thing to investigate, as they can lead to brittle failures. The chemical and physical processes associated with AAR have now been the subject of considerable research, but there's a current lack of knowledge with the actual implications on shear performance of affected concrete structures.
