Mineralogical analysis of mortars in the walls of Ávila (Spain) and its surroundings

The present article evaluated the mineralogical composition of 85 mortar samples from some emblematic monuments of Ávila city (Spain), which were collected during the restoration of the monuments. The aim of this article is to try to extract the relationship between the composition and the origin of...
