Evaluation of the Effectiveness of Natural Stone Surface Treatment From Ukraine by Mechanical and Chemical Methods

Abstract

Studies have been conducted with the aim of studying ways to improve the decorative properties of natural stone products. That will allow to make a nished product run of natural stone with a homogeneous tint. For this purpose, the indicators of lustre, lightness and saturation of natural surfaces of facing stone worked by mechanical and chemical methods are described. The in uence of chemical treatment on the decorative indicators of various kinds of natural facing stone depending on its mineralogical composition is determined.

Applied scientific and systemic problems of the related ore-dressing plants interaction in the event of decommissioning the massif that separates their quarries

“…The issues of resource-commodity interaction of mining and processing enterprises (MPEs) as components of precisely a single systemthe mining and metallurgical complexwere resolved very superficially. The possibilities of technological interaction were not almost studied at all, despite the fact that the quarry fields of some of the neighbouring ore mines were mined out more and more intensively [1]- [6]. However, in the conditions of mutual overlapping the zones of technological impacts of two quarries, fundamentally new problems arise, especially when using mass explosions.…”

Analysis of change in the decorative properties of granites under thermal exposure

“…People built a considerable number of architectural monuments using facing rocks. Taking into consideration their considerable age, questions arise regarding their restoration [1]. There are certain possible problems: deposits ceased to develop, or deposits develop other horizons.…”

A study of indicators of expected operational losses in the extraction of block raw materials with disk stone cutting machine

“…При плануванні гірничовидобувних робіт на кар'єрах декоративного каменю основоположним є тріщинуватість масиву, розміри блоків, що видобуваються, фізико-механічні властивості каменю. І вже залежно від цих факторів планується напрямок фронту гірничих робіт, висота уступів, обладнання для видобування та транспортування [1][2][3][4][5][6][7][8][9].…”
