To gain additional data on the mineralogy and elemental composition of the mortars, select uncovered thin sections were analysed after coating by carbon evaporation by scanning electron microscopy (SEM) coupled with an energy dispersive spectrometer. Scanning electron microscopy was especially used to visualise the surface structures of magnesium-rich lime mortars. A connected energy dispersive X-ray microanalysis (EDX) was used to show element distributions to derive conclusions about possible crystallisation processes. 3.1.3 Investigation of physico-mechanical properties The samples reported here were selected because they represent the most typical aggregate-free bedding and pointed mortars. With the further analyses presented here for the first time, the special features in the composition are investigated more closely than in the past. Some soil consultants might use different numbers but everyone knows you need way more calcium than magnesium. Warr, L.N. (2021). "IMA–CNMNC approved mineral symbols".

Particularly dense microstructures and high compressive strengths at specific points can be measured on mortars made from dolomitic limestones, which are not described in more detail here.

The contents of CaO and MgO were calculated, and the method was specified according to Middendorf et al. ( 2005a, 2005b, 2005c). For this purpose, atomic absorption analyses of the carbonate binders and qualitative X-ray diffraction (XRD) were performed to determine the phases.Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. [1] The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. [2] [3] The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. [4] [5] Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which indicates that some past dolomite deposits may be due to microbial activity.

To obtain further information on the binder type and aggregates, individual samples were examined microscopically.
