Description
Shell rock is called the special kind of limestone, mountain sedimentary breed. Feature of a shell rock is that it consists of the sinks pressed during the millennia and their fragments belonging to once sea inhabitants. Structure of a shell rock porous. Such rocks as a shell rock (a rakushnik, rakushnyak) are called breeds of a zoological origin in geology.
Structure of a shell rock - it honor a calcium carbonate for 100%, but there are at it also small amounts of salt and iodine. It gives to a shell rock bactericidal properties. At the rooms revetted with a shell rock from within there are always insignificant iodide evaporations and evaporations of chloride of sodium that makes salutary impact on cardiovascular system of the person.
It is possible to call a shell rock owing to its porous structure the natural filter which is not passing in the room of harmful substances from environment. The shell rock is eco-friendly. He possesses perfect inertness and does not enter interaction with components of finishing and construction materials. Such property of a shell rock as thermal stability, allows to use it for art finishing of fireplaces. Other property - resistance to attrition - does a shell rock by ideal material for facing of steps of ladders.
Porosity of a shell rock provides its good warm and noise-insulating properties. In the house built of this stone it is not necessary to apply additional heat insulators and protection against noise. Besides, the shell rock is considered one of the few natural materials capable to provide antiradiation protection.
Fields of a shell rock are in the Crimea, in Kazakhstan, in Moldova, in Azerbaijan, in the Donetsk and Odessa regions of Ukraine. As transportation of a heavy stone on long distances cost much, a shell rock far earlier and did not carry, and built of it houses near places of production of a stone. Perfectly mansions from a shell rock in Baku, in Odessa, in Chisinau, constructed more than a century ago remained.
Now transportation of a shell rock stopped being an unsoluble problem, and it is widely used for construction in a midland of Russia. But climatic conditions here others, than in the south, within a year the large number of rainfall drops out. That the porous shell rock did not absorb moisture, it is necessary to cover structures from it water-repellent, or hydrophobic, with impregnations. It much more will increase service life of the southern stone.
