AbstractAbout AuthorsReferences
Data on the situation in the construction industry and present needs in rocks for producing the crushed stone with high physical-mechanical characteristics, which deficit is partially covered due to the import from other countries, are presented. As a perspective object for expansion of the mineral raw material base of the North-West of Russia, archean silicites have been studied. General information about rocks and their geological-mineralogical characteristics is given. Results of the recently conducted research in the structure, compositions, and physical-mechanical properties of silicites, as an untraditional raw material of quartz-field spar composition, are presented. It is shown that these rocks in their natural form are suitable for producing the high-quality crushed stone in accordance with technical requirements. High acid-resistance (>97%) makes it possible to use the ground silicite in acid-resistant con- cretes, mastics and as a filler in lacquers and paints.
