Assessment of Mechanical and Physical Behaviour of Sandstones Through Quasi Non-destructive Tests

Marco Ludovico-Marques, Carlos Chastre

Research output: Chapter in Book/Report/Conference proceedingChapterpeer-review


An experimental programme was carried out in order to assess physical properties, such as porosity and mechanical behaviour, through compression and drilling strength of sandstones, classified as lithic arkose. These stones are similar to those found on St. Leonard’s church at Atouguia da Baleia village in the Western region of Portugal. This monument’s façades were selected because of the extent and depth of the most important degradation pattern exhibited, the alveolization. The Drilling Resistance Measurement Test is an important way to survey the extent of stone weathering on historical building stones due to the correlation of porosity and compressive strength with the drilling strength parameter. It is also a less intrusive and quasi-non-destructive portable test. The drilling time is even lower than other tests duration for lower porosity materials. Absolute differences between experimental and predicted values of porosity obtained on these sandstones through correlations with drilling strength are in general lower than 13%. Considering the best correlation, these absolute differences are up to 6%.
