Travertine, tuff, basalt
Travertine - a lightweight porous rock, which is a point accumulation of calcium.
Travertine is used as a decorative and building natural facing stone for exterior and interior finishes administrative and residential buildings, flooring, decking pools.
Natural travertine stone does not contain substances harmful to humans, and therefore so is widely used in the decoration. Beautiful warm tones of travertine slabs create a unique feeling of comfort and coziness.
Travertine or tuff – He no longer limestone - "stale" in the bowels of the earth a couple of centuries and has not yet marble - missing a few thousand years before the state of marble. Accordingly, it has a somewhat similar features as with limestone and marble with Buy or order travertine can be in our online store
Tuff
Tuff (from Italian. Tufo) — light, cemented, porous rock. Having high decorative properties, represents a valuable building material finishing. By the method of geological formation distinguish the main types of tuffs: volcanic, calcareous and siliceous. Calcareous and siliceous tuffs form, unlike the volcanic tuff, a group of rocks, united genesis - the deposition of calcium carbonate or siliceous material from a solution in places out of the earth's surface mineral springs. Masonry of tufa formation conditions in the weathering of rocks water dissolved chemical compounds, forming a solution which is then there is a secondary precipitation and the formation of new rocks. If deposits are the result of inorganic chemical processes, the formation of "scum" and tuffs. In places of the earth's surface water sources and the pressure drops of a solution of carbon dioxide is removed, thereby dissolved in water compounds decompose and precipitate in the form of calcareous or siliceous tuff. Tuffs of the caves can be formed stalactites and stalagmites.
Deposits
Known deposits of tufa in Iceland, Italy, Kamchatka (Valley of Geysers), in New Zealand, Armenia (Artik), USA (Yellowstone National Park).
Benefits tuff as finishing construction material
• Durability. • Durability. • High frost (50-600 cycles). • Excellent sound insulation and heat insulation. • Good water resistance. • Small bulk density (t/m3 0,75-1,6). • Tuff superbly resistant to heat, frost and moisture. • Tuff very easily handled. • Tuff superbly saved under different atmospheric conditions. • Tuff has a high resistance to weathering, which keeps it in good condition for many years.
