| you are: Kinds and application of natural stone materials
Natural stone materials apply in considerable quantities to a construction of dams, moorings, piers, piers, sluices. In a zone of a variable water level of a condition of service of a material are especially adverse: the stone tests repeated freezing and thawing in the condition sated with water. 123456 protective facing in this zone arrange from dense izverzhennyh the breeds having water absorption no more 1%, mark on durability - not more low 800-1000 and on frost resistance - of Mrz 150 MrzZoO depending on a class of a construction, climatic and other service conditions. To corresponding requirements should satisfy and materials for stone nabrosnyh dams. 123456 internal parts can be made a sketch of a stone received from sedimentary breeds М300-600 with factor of a softening not less 0,7-0,8. Stone materials check on influence of the substances dissolved in water (sea, soil, river, marsh). 123456
The Onboard stones separating a carriageway from sidewalk, izgotoeljajut from dense izverzhennyh breeds (a granite, diabase, etc.), different high morozo - both wear resistance and durability. BortoEye stones happen straight lines and lekalnye, high - to 40 sm and low - to 30 123456 These stones see apply instead of concrete at the corresponding feasibility report.
