Method and system for providing a decision aid for the user, for the selection of, in a building material region - the borehole surface to be used and / or cutting elements

摘要

The present invention relates to a method and system for providing a decision aid for the user, for the selection of a building material to be used in the region of the borehole surface and - and / or cutting elements, in which, in a geographical information carrier (10) areas of use of additives for concrete as a function of the different drilling - and / or cutting resistances of the aggregate in regions (12, 13, 14) are divided. In this information carrier, each of the aforementioned areas (12, 13, 14) in each case a marking (15, 16, 17) associated therewith, each of a drilling - and / or cutting resistance, contrary to give a certain size, and in which the, in a field of application of additives specific drilling - and / or cutting resistor - the borehole surface to be used and / or cutting elements with a, to the identification (15, 16, 17) of the regions corresponding identification (25, 26, 27), are provided.
