Estudio de morteros para reparación arqueológica y patrimonial : Ceniza Volcánica.

Abstract

The current curricular integration project encompasses the development of mortars composed of slaked lime, volcanic ash, and sand, to investigate and evaluate their behavior in applications on archaeological and heritage structures. Additionally, analyses of the mechanical properties will be carried out through tests compliant with the American Society for Testing and Materials (ASTM C109/C109M). The research focuses on examining how the incorporation of volcanic ash modifies the properties of the slaked lime mortar, considering the enhancement of mechanical strength of the structures, reduction of cracks, mortar permeability, and compressive strength. In this study, the selected mortar is produced from slaked lime obtained by hydrating quicklime over a period of 60 days. The mortar mixture incorporates different weight replacement percentages of lime with volcanic ash (5%, 10%, and 20%). To evaluate their properties, tests were conducted on cubes of slaked lime mortar at ages of 28, 56, and 90 days.
