Abstract: Workability of masonry mortar is an important concern for masons, contractors and producers of mortar, in
new construction as well as for restoration. The definition of workability has been an issue in the literature
on building materials for the last decades, and attracted special attention from normalising institutions, with
the predominant aim to develop suitable measuring methods. When applied to different types of mortar, the
shortcomings of these methods often appear. We attempt to provide a basis for the definition of workability
starting from a medium scale practical experiment with six masons and six different types of lime and
cement mortars. It appears that, despite the obvious existence of personal and national or regional accents, a
general correspondence can be found in the masons' appreciation of different mortars. The preferences of a
group of the test panel are consistent, and allow to draw up a series of properties, which together give a complete
image of workability. The analysis of the results leads to the classification of these properties in rheology,
hygric properties and density, which interact in a complex manner.
