Mortar, and aggregates (Figure three). As outlined by the results, sample surfaces have been covered by a layer of biological sediments (black spots) on outdoors. The calcite content material detected in samples was considerable. The most important obtaining was the presence of animal fibers (up to 5 mm) within the mortars. Sea sand (up to two mm) or river sand (1.5 mm) were also employed as aggregates.Heritage 2021,Heritage 2021, 4 FOR PEER Overview Thesemortars contained ceramic fragments of 800 in diameter, and marine shells up to7 10 mm; microcracks and calcite grains have been also observed in the mortar structure.Figure three.
