The results of bulk densities and capillary water absorption from selected mortars are reported in Table 1. As the light microscope can visualise voids with a size of > 10 − 6 m, only a few capillary pores (10 − 5 m – 10 − 8 m) are visible. Instead, mainly limestone relicts, partly over— or underburned lime putties and a small number of aggregates are embedded in a homogeneous crystalline binder matrix.

Leitfaden Naturstein-Monitoring - Nachkontrolle und Wartung als zukunftsweisende Erhaltungsstrategien. Little dolomite is found in Cenozoic beds (beds less than 65 million years old), which has been a time of generally low sea levels.The preservation of the original limestone texture can range from almost perfectly preserved to completely destroyed.

The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. In old USGS publications, dolomite was referred to as magnesian limestone, a term now reserved for magnesium-deficient dolomites or magnesium-rich limestones. Microscopic proof for clearly separated Ca- and Mg-enriched phases indicate crystallisation process that proceeded separately. In consultation with the project partners, bedding and pointing mortars were selected for the samples (Fig. Such mixtures are the consequence of the infringement of a dominantly siliciclastic depositional setting (e.

In SMT as well as in JMY, microscopic evidence of a very dense, crack-free microstructure due to post-slaking periclase (MgO) is found. Effects of early diagenesis on Mg isotopes in dolomite: The roles of Mn(IV)-reduction and recrystallization".
