摘要

A new portable system (DFMS) has been developed and validated for directly determining stone mechanical features such as the "hardness" by measuring its drilling resistance. The test is essentially non-destructive, since stones can be tested, with only minor patching of holes (Φ 5 mm) on exposed faces. With this system it resulted possible obtain affordable and sensible data of the mechanical and abrasive properties of stone specimens and monuments and to evaluate the consolidating performance of applied conservative treatments. The DFMS has not competitors for its application in comparative tests "in situ" and it has been suggested as standard method, to UNI Normal (Italy), for assess the quality assurance of consolidating treatments. Furthermore, preliminary results obtained with standard operative conditions seems indicate its possible application as portable diagnostic tools for determining the UCS directly in quarry.
