Development of repair mortars for the restoration of natural stone in cultural heritage

The aim of the research project RESDOSYS is the development of a repair mortar system on a modular basis. To archive this, various parameter studies will have to be conducted. The experimental studies, which are presented in this paper, deal first of all with the development of a useful basic-mixture that allows the comparable execution of parameter studies in regard to different fields i.e. influence of the sand, of the binder of inert powders, pigments admixtures etc.
