Visiting the capital of Armenia, the city of Yerevan, it is impossible not to pay attention to the wonderful monuments of ancient architecture. Most of them are built using the ideal on their decorative and technical properties of stone – Armenian tuff.
Tufa is a light storing porous rock. It is formed as a result of ingressing the substances of magma. Distinguish lime (or carbonate) tuff, silicon (fellsite), volcanic. Lime-based species are something average between marble and limestone. Natural deposits of this stone are located on the territory of Italy, Iran, Turkey, but most of the world’s wealth (about 90%) lies in Armenia.
Armenian tuff refers to a group of rock stone rocks formed from volcanic ash, often its composition and density are inhomogeneous, depending on the type of mother breed and interval intervals. The common property is always a porous structure, since the rock rocks of the volcanic type consist of the impact of small fragments, ash, as well as sand. Porosity gives the stone perfect water and frost resistance. In addition, this material is light and soft, which allows processing, without applying complex building tools. It is usually enough to have only an ax and a saw.
Tufy, sitting in Armenia, surprisingly beautiful. It is believed that this stone can have up to 40 different shades.
The combination of porosity with a soft color palette creates a unique, striking look design.
Armenian tuffs, depending on their natural and mechanical properties, is customary to classify.
- Anonya tuffs. They have a yellowish orange or red shade. This is the easiest water variety by weight.
- Artiksky. Such tuffs are characterized by pink, brown or lilac. This is the most famous diverse appearance, no wonder Yerevan because of the abundance of such buildings is called a pink city. The artist deposit refers to the largest in the world.
- Yerevan tuffs. Look like beautiful black and brown or red stones. Actively apply in facing works.
- Burakan. Tufy having many engines of minerals and stones. They are also characterized by stains of various shades, most often brown and yellow-brown.
- Felzite tuffs (Martirosky and Noemerbanian). Dense, unlike volcanic, beige color stones with yellow or golden-red splashes. Often have brown-brown patterns, which is explained by the presence of iron.
Thanks to simple treatment, porosity, lightness and diverse shades, Armenian tuff is most often used for construction and facing. Hard species except those listed above have high seismic resistance. The numerous architectural monuments of the ancient architecture of the Armenian people, such as the Cathedral in Echmiadzin, built in 303, are evidenced about the beautiful physico-mechanical properties, strength and frost resistance of the tuff. N. NS. From this stone make walls, supports for domes and roofs, they are facing floors, ceilings and walls.
In its characteristics, this stone has similarities with facial brick, but more frost tuffs, durable and water vehicles. Houses built from Armenian tuff have good sound insulation and ideal for any weather conditions: in the summer they are cool in them, and in winter it is always warm. It is used for outdoor masonry, facing of fireplaces, from it the windowsills and columns, wine cellars. Due to its decorativeness, it is widely used in landscape design: benches, tables, couch, sculptures profitably emphasize the beauty of greenery, colors and very durable. Tuf is perfectly combined with glass, wood, metal, stones.
Architectural buildings from Armenian tuff is outside of this country.
The most famous UN headquarters in New York, the building of the Ust-Ilimskaya HPP, at home in Novy Urengoy, facades of buildings in St. Petersburg, an administrative structure on measnitskaya Street in Moscow. All structures from this amazing stone personify strength, durability and beauty.
