Producition Of Facing Stones Of Georgia
| Discription of the propozal: |
Organization of marmorised limestone’s and tuff slabs production in Georgia. |
| Justification of the propozal: |
Attraction of the proposal is defined both by the variety of building and facing stones (including counted supplies as well as half-studied ones) on the territory of Georgia and higher realization prices compared with their prime cost. It should be noted, that above mentioned stones differ in color shades, strength, endurance and conditions of season works. |
| Implementation of the propozal: |
Manufactured goods – Production of Blocks and slabs of marmorised limestone’s and tuffs (European standard) on outcrop, that will be transported to Tbilisi (due to season work worsening) and there will be realized their final treatment (polishing) and storing. According to infrastructure and communications Georgia has advantageous geographical distribution: access to the Black Sea (Batumi and Poti ports) and countries of Asia. Manufactured goods should be realized on Georgian market and exported by investor. Areas and samples that are mentioned below are perspective areas and their manufacturing is possible in a short time. |
| Estimated cost: |
The full investment represents US $ 2 000 000, time of a covering of the investment (at serviceable work of manufacture both duly export and realization of production by the investor) - is 2.4 year. |

CHOBARETI MARBLELIKE LIMESTONE DEPOSIT
|
Location of a deposit or
occurrence
|
Characteristic of a mineral deposit
|
Physical-mechanical properties of mineral deposit, chemical composition and compliance of raw material with GOST (State Standard)
|
|
The deposit is located in Akhalkalaki region to the NW 7 km of Azavreti vil. at the altitude 2100-2200m s.l. The distance from the deposit along the automobile road to the Akhalkalaki railway station is 22 km and to the seaport of Batumi is 230km.
|
It is uniformly, fine-grained ivory-white limestone like marble. The output of fragmental stone from rock mass is 35.2%.
Units of IV- V groups predominate. The output of plates from 1 m3 of fragmental stone is 24.2 m2. The quantity of reserves of B+C1 category (provision resources) amounts to 5180 thousand m3. The number of units is – 994 thousand m3.
|
The rock is easily worked, after polishing it takes on smooth surface (luster). Volumetric weight - 2610-2716 kg/m3 Specific weight - 2730 kg/m3 Water absorption - 0.22-0.56% Porosity - 1.11-4.01% Compression strength : a) in air-dry state - 536-666 kg/cm2 b) after 25 cycles of freezing - 428-561 kg/cm2 Softening coefficient - 0.86. Abrasiveness - 0.84 - 1.15 g/cm.
