“…The endothermal peak at 580 ο C, not accompanied by any mass loss, is attributed to the transition of quartz-a to quartz-b. The high values of CO 2 loss (>600 ο C), corresponding to the decomposition of calcium carbonate, in combination to the high reverse hydraulicity index calculated in the cases where no decomposition of organic matter was noticed, further confirms the classification of the mortars as lime mortars (Table 2, Fig.5) [24]. Furthermore, the mortar aggregates are solely calcitic in the case of samples ΜΚ1, ΜΚ2,ΜΚ2b, ΜΚ4, whereas in the rest of the samples, aggregates are a mix of calcitic and silicate nature.…”

“…The pozzolanic peaks in these regions are attributed to several calcium aluminium silicate hydrates (CSH, CAH, Tb, CACH), which bind water (Moropoulou et al 2003). Weight loss by temperatures at 750°C corresponds to recarbonated lime including cementious material and in case of limestone clay also minerals (Moropoulou et al 2003).…”

“…Table 1 shows the weight loss of the samples, which have a very high and different weight loss at 750°C. After Moropoulou et al (2003), mortars with a weight loss of more than 8% can be classified as 'cementious'. But the high differences also suggest that factors other than structural-bound water are responsible for the weight loss.…”

Qadhat is the name for a lime mortar in Southern Arabia. Its usage has a long tradition. This work describes physical and mineralogical properties of ancient, historical and new samples, which seem to have been produced the same way. XRD, thin sections and SEM analyses show the similarity of the material. It consists of aggregates of volcanic material that are rich in volcanic glass and lime as binder. The production process includes several hours of crushing the material, which produces fine-grained splinters of aggregates in the binder matrix and gives the mortar a high stability. A weathering test with sodium sulphate on different samples confirms that the stability of this mortar is the result of the production process.

Mineral building materials are generally heterogeneous and porous solids. Their engineering properties are closely associated with their porosity and pore‐size distribution, which can be studied by mercury intrusion. The entire pore‐size distribution curves are used to determine changes in the pore structure of a material class in a qualitative way. Certain parameters derived from pore‐size distributions can be correlated to engineering properties. These key values are applied as criteria to evaluate the quality and durability of a building material. However, because of the heterogeneity of natural and artificial building materials and the influence of moisture content on their pore structure the results are strongly affected by preparation conditions such as sampling and drying. A correct analysis requires a knowledge of these effects. The paper describes the use of mercury porosimetry to study mineral building materials such as cementitious materials, bricks, and renderings. Furthermore, the influence of preparation effects on the precision of measurements is discussed.
