The graph below shows the result of CVR1's diffraction spectrography.

CVR 1 is a mortar for stone or brick masonry grouting (more traditional product).

CVR 2 is a fiber reinforced natural mortar based on natural hydraulic lime.

Below the diffraction spectrography of CVR2 is depicted.

CVR 3 is a natural mortar based on natural hydraulic lime designed to carry out restoration work for historic buildings.

The figure below reports the shear viscosity as a function of shear rate for sample CVR 3. The viscosity ranged from 4300 to 1 Pa·s for a shear rate variation from 0.1 to 100 s^-1. The reported values indicate a mortar with good workability.

The picture below shows the diff...

CVR4 is a natural lime-based mortar designed to carry out restoration work for historic buildings with a specific care for natural products.

GCP7: Mortar from an internal room of the Gubbio Consoli Palace.

Mortar consisting of 30-40% in volume of aggregate with a grain size in the field of fine to coarse sand (0.1-1.5 mm, with most of grains < 1mm in size), moderate to scarce sorting, roundness variable from angular to sub-rounded, average to low sphericity and no preferred orientation of the grains (Fig. 13). The aggregate is composed of lithic fragments, monocrystalline grains and diffuse calcium carbonate remains of organisms (mostly planktonic foraminiera, Fig. 15). The dominant lithol...

GTW1 is a mortar from the Gubbio Town Walls, Section Cassero.

It is a mortar consisting of about 50% in volume of aggregate with a grain size in the field of average to very coarse sand (0.2-2.3 mm). The picture below on the right shows the diffraction spectrography of GTW1.

Moderate to scarce sorting.

Roundness variable from angular to sub-rounded Low sphericity.

Without preferred orientation of the grains (see left picture below).

The aggregate is composed of lithic fragments (biomicritic limestones, cherts, arenites and rare me...
