Method for determination of fracturity of blocks and articles made of natural stone includes cleaning of surface of block or article with removal of dirt, application of penetrant that glows under effect of ultraviolet radiation to it in such way that is fills cracks. One removes residues of penetrant from surface of block or article, after that one applies developer to it, this takes out penetrant from cracks, with determination of characteristics of fracturity of block or article, after that one performs end cleaning of block of article with removal of penetrant and developer. Characteristics of fracturity of block or article are determined through performing in sequence operations of formation of video image of surface of block or article by means of device for formation of video-images and source of ultraviolet radiation and entering formed video-image to computer medium of digital electronic computing machine, with reveal of cracks on that image, their thinning to broken line with following determination of geometrical characteristics and fractal dimensions, on basis of those one determines characteristics of fracturity of blocks and articles made of natural stone. |
