Sobre as possíveis fontes das pedras do Mosteiro de Salzedas (Tarouca - Portugal)

O Mosteiro e Igreja de Salzedas situam-se sobre o Granito de Penodono-Salzedas-Alvite, que neste local se apresenta muito meteorizado e fracturado. A utilização de elementos petrográficos permitiu discriminar diferentes tipos de granitos nestes monumentos e, com informações topográficas e históricas, propor possíveis relações com pedreiras próximas.

Prediction of the mechanical properties of granites by ultrasonic pulse velocit...

The present work deals with the use of simple and economical non destructive techniques, ultrasonic pulse velocity and Schmidt hammer to predict the strength and elastic properties of granitic stones that are characteristic in ancient masonry constructions. Good correlations between NDTs and strength and modulus of elasticity were found, which indicate them as appropriate techniques for estimating the mechanica...
