ABSTRACT
Different types of rocks and loose natural aggregates (sand and gravel) may exhibit different chemical and physical phenomena leading to their destruction and in the case of applying aggregates in construction elements (concrete forms, read and railway facilities) the phenomenon leading to their destruction. They affect the safety of buildings and also provide a substantial cost factor in their use. Thus, early detection of destructive phenomena at the stage of exploitation and processing of aggregates and rock and the application of effective methods of preventing them is a necessity.
