>Соответствие гранита Жельтау требованиям ГОСТ 9480-2012 (плиты облицовочные из природного камня)
The granites zheltau according to the requirements of standard 9480-2012 «Plates facing made of natural stone»
From 01 July 2013 entered into force the revised GOST 9480-2012 "Plates facing made of natural stone". The effect of GOST apply to veneer, intended for interior and exterior facing, flooring, slabs and slabs for processing at the architectural and ritual articles.
To facing plates possessed the requisite strength and durability, for their production you only need to use granites with high quality physical-mechanical characteristics and is resistant to repeated repeating cycles of freezing/thawing. Quality requirements for raw materials of tiles and slabs in GOST 9480-2012 is that raw materials for the production of facing slabs must conform to rocks described in GOST 9479-2011 "Blocks from rocks for manufacture of facing, architectural-building, memorial and other products".
Granite deposits Zheltau-1 Red Zheltau-2 Yellow, Zheltau-9 (trade name "Zhalgyz") array Zheltau of the Republic of Kazakhstan is already widely used stone processing enterprises in Russia and actual use is growing rapidly. In this regard, becomes relevant question about the applicability of these granites for the manufacture of tiles. Carry out a comparative analysis of requirements of GOST 9479-2011 to solid rocks, which should correspond to the granites used for the production of tiles and slabs, and actual strength characteristics of granite deposits Zheltau-1 Red Zheltau-2 and Zheltau Yellow-9 ("Zhalgyz"):
Comparative analysis shows that the granites Zheltau-1 Red Zheltau-2 and Zheltau Yellow-9 ("Zhalgyz") satisfy the requirements of GOST 9479-2011 "Blocks from rocks for manufacture of facing, architectural-building, memorial and other products" to the rugged rocks used for the manufacture of tiles and slabs. However, the total analysis of physical and mechanical properties of granites Zheltau shows that the Kazakh group granites Zheltau have strength properties far exceeding the requirements of GOST 9479-2011 and even GOST 32018-2012 instituting more demanding requirements for strength of granite The granites zheltau according to the requirements of 32018-2012 «Product road-building from a natural stone».
Given that granites Zheltau-1 Red Zheltau-2 and Zheltau Yellow-9 ("Zhalgyz") for specific effective activity of natural radionuclides belong to class I (safest), which has no restrictions on use in the construction, decoration and road construction in accordance with SanPiN 188.8.131.5200-10 "Hygienic requirements to limit public exposure from sources of ionizing radiation", we should conclude that the granites Zheltau-1 Red, Zheltau-2 and Zheltau Yellow-9 ("Zhalgyz") can be applied to all areas using natural stone and have no restrictions on their use in accordance with the normative documentation of the Russian Federation.
In the North-Western region in St. Petersburg (Vsevolozhsk) operates Russia's largest warehouse of granite blocks Saltau of the Republic of Kazakhstan. Wholesale treasure blocks our company has more than 1.500 m3 block of granite Zheltau, rare red-pink, yellow and beige at affordable price.
