Abstract: 
In the scope of a recent research project investigations on the performance of repair mortars for concrete structures were carried out at BAM. One of the key points of the project was the systematic investigation on the mode of action of single constituents and their interactions with special emphasis on their influence on the mortars’ stiffness and shrinkage behaviour. The mortar’s shrinkage can be the reason of many following problems, which can be a direct result, i.e. the damage of the bond interface caused by constraining forces, or an indirect result, such as an increase in carbonation depth or chloride penetration due to shrinkage induced constraining cracks, which will subsequently lead to durability problems. Especially when repairing weak substrate concretes the proper adjustments of the mortar’s stiffness and shrinkage behaviour to the properties of the concrete is of essential importance for functionality and durability of the repair task.
