Because of this the utilisation of identical material is a main objective of restoration. In consideration of this goal, high-temperature gypsum plaster has been tested in pure and modified varieties. According to the historical standard, high-temperature natural gypsum (Keuper (Triassic)) mixed with non-hydraulic lime and crushed gypsum stone to different ratios was used. The substantial interest is focused on the influence of the hydrated lime concerning physical and hydraulic aspects. Also the differences in the manufacturing method (e.g. duration of mixing) were taken into account. Investigations regarding thermal and hygric change in length, biaxial flexural strength and compressive strength, dynamic E-Modulus, water absorption, frostthaw-change resistance were carried out. The aim of these investigations is to prove appropriate gypsum mortars for the exterior and the interior application respectively to initiate further research into conservation and restoration of gypsum.
