The effective design of a mortar for repairing masonry depends on a clear understanding of its function within masonry. The functions of mortar materials in masonry are classified as bedding, pointing, grout, render, plaster and mortars for surface repairs. The requirements that each type of mortar must meet in service depend on its environmental exposure and its role in the structural integrity of the masonry element that it is found within. Technical requirements such as adhesion, strength, elasticity, water and vapour transmittance, drying behaviour, thermal dilatation, ability to deal with salt contamination and freeze-thaw cycling, and its aesthetic properties can be quantified. Different functions of mortar will be utilised in different repair interventions in masonry structures depending on these requirements. Mortar properties can be adjusted to meet technical requirements through the use of different binder and admixture types.
