Mortar, and aggregates (Figure three). In line with the outcomes, sample surfaces have been covered by a layer of biological sediments (black spots) on outside. The calcite content material detected in samples was considerable. One of the most important acquiring was the presence of animal fibers (as much as five mm) in the mortars. Sea sand (as much as 2 mm) or river sand (1.5 mm) have been also applied as aggregates.Heritage 2021,Heritage 2021, 4 FOR PEER Critique Thesemortars contained ceramic fragments of 800 in diameter, and marine shells up to7 ten mm; microcracks and calcite Polmacoxib Protocol grains were also observed in the mortar structure.Figure three.
