Nondestructive Quality Testing of Natural Stone Blocks

I. V. Pavlov, A. A. Irkanaeva

The age of Karelian granites is estimated at 700 mil years. During that time differently directed internal stresses have accumulated in the rock massif. Extraction by explosion or by diamond-rope sawing adds extra stresses which result in formation of various defects, especially microcracks that are invisible but have an influence on a final product. The matters of nondestructive quality testing of granite blocks are considered in the article.
