“…Besides, aggregate size also contributes to material reactivity, since the smaller the size, the higher the specific surface area and thus the higher the reaction rate [8,[46][47][48]. Furthermore, mortar porosity is lower in mortars with better-sorted aggregates since they produce a better-packed system [49][50][51][52].…”

Mortars from the cistern in Amaiur Castle (Navarre, Spain) were analysed to assess the mortar manufacturing process and application techniques. To this end, optical microscopy, scanning electron microscopy (SEM), thermogravimetric analysis, X-ray fluorescence (XRF), X-ray diffraction (XRD), Raman microspectroscopy, and Fourier transform infrared spectroscopy (FTIR) were performed. The study of both structural and plaster mortars from Amaiur Castle cistern show patterns/rules in the mortar manufacture according to the specific construction requirements. A multilayer application technique was used for the construction of the cistern tank. Deliberate selection of the aggregate nature and grading contributed to mortar impermeability. Ceramic and silico-aluminous rock fragments were used as aggregates in the cistern tank to confer hydraulicity to the mortars, instead of carbonated aggregates as used in the vault. Aluminosilicated phases present in the aggregates led to the formation of amesite, which is a magnesium aluminosilicate hydrate (M-A-S-H) phase conferring hydraulicity to the mortar. Two types of additives were identified in the outer pigmented layer of plaster. Beeswax was the identified organic additive used to improve the impermeability of mortar, while hematite was the identified inorganic additive giving rise to the reddish colour of the layer.

The 1.2µm and 100µm silicon carbide were prepared by the process of reshaping and classification. The effect of particle morphology and particle size distribution of silicon carbide on tap density, green body density and apparent viscosity of slurry were analysized. The result showed that the particle size distribution closed to normal distribution and the particle morphology closed to spherical were the main cause that leads to the lower apparent viscosity and the higher density of the green body.
