Abstract: Although much research work and experience have been accumulated during the last forty years the design and manufacture of the above mentioned mortars is still problematic. This has a direct impact to the quality and cost of restoration work as well as to the preservation of the authenticity of the monumental structures.
This could be attributed to a series of reasons which converge to the ascertainment that the design and manufacture of these mortars has not been established on a scientific footing to be comprehensible. The widely accepted concept of compatibility between existing structure and new repair materials has not been clarified in technical terms. The criteria for suitability of the raw materials used for manufacturing these mortars are not adequate or well defined. There are no constitutional laws or basic relationships concerning the parameters that influence the performance of them so as the design to be based on them.
The lack of a manual of practice including recommendations, instructions simplified methods of checking in place the manufacture and application of these mortars is obvious in restoration works.
In this paper firstly a review made of how the problem has been occasionally anticipated, then the main questions about the design, manufacture and application of these mortars from the technical point of view are discussed.
Finally, a process followed for proportioning of repair mortars in many case studies (in which the role of mortar in the structure was different) is presented.
