Testing of mechanical properties of natural stones used as a building material

Abstract eng:
Further presentation of some destructive and non-destructive methods for investigation of mechanical properties of natural stone quarried and used as a building material in Bohemia in the past is the aim of the paper. Tested samples were made both from virgin material from existing quarries (e.g. sandstone from Hořice) and from material got from historical constructions (various sandstones from the Charles Bridge in Prague), which was built-in for a long time. The flexural strength, the compressive strength and Young modulus were obtained from the basic destructive tests. Before these tests the identical samples were investigated non-destructively by ultrasound and so called peeling test so that the two ways of testing could be compared at the end.
