External facing of buildings can be carried out from weatherproof sedimentary breeds (limestones, dolomite, sandstones, tufov) which give in to processing is easier and is more economical than granite breeds. For internal facing of public buildings and constructions (for example, underground stations) widely use the plates received from well sawn breeds: marble, anhydride, plaster.
Plates for external facing have a thickness 4-8, for internal - 1,2 - 4 Application of diamond cutters see allows to produce thin (5-10 mm) the economic plates, which cost in 2-4 times more low, than usual. Thin plates find wide application, especially for internal facing.
Special facings apply to protection against corrosion and action of heats. For protection against solutions of acids {except fluoric and kremneftoristovodorodnoj) use andezit, a granite, sienit, diabase, quartzite, siliceous sandstone and others kislotostojkie breeds. Rubble from these breeds serves as a filler in kislotoupornom concrete. In heatproof concrete use fillers from such breeds (hromita, basalt, diabase, a tufa) which do not contain some quartz.
Socle plates, and also details of eaves, corbels and other acting parts of constructions produce from proof breeds. These products should not have hair cracks, it gives such form that on them water from a rain and thawing snow was not late.
Plates for floors and stone steps of internal ladders should have high wear resistance and the decorative properties corresponding to architecture of an interior.
