Basic data on the weight of granite and marble for calculations

The thickness of 1 cm is 27 kg / m2, the thickness of 2 cm is 58 kg / m2, the thickness of 3 cm is 85 kg / m2, the blocks are 2700 kg / m3
1. Calculation of the marble area - The length is multiplied by the width.
2. Calculation of the block volume - The length is multiplied by the width and multiplied by the height
Attention! The above is the size of the block by which the cost is considered, in fact, the real weight of the block must be considered at the rate of 3200 kg / m3, since on each side there is a margin for the undercut

Quality grades and prices for marble Crema Marfil marble

The price of marble Crema Marfil depends on the cleanliness of the slab surface, the cleaner and more uniform the material, the more expensive the more gray clouds, veins and wreath, the material is cheaper.In the classical scheme there are six grades of varieties: Extra, 1 choice, High standart, Standart, Commercial, Clasico.Caution!Some factories come up with fictional names for varieties, especially leaving the classical scheme to erase such a strict framework of gradation.

The main types of final processing of natural stone

1. Sawn - is formed after cutting blocks of natural stone with diamond circular saws. Non - uniformly rough surface with longitudinal grooves and height differences up to 5 mm.
2. Polished texture - differs mirror image of the surface of natural stone, a clear reflection of objects, without traces of processing the previous operation. Polished texture is achieved using special abrasives. Polished glossy surface completely reveals and emphasizes the natural color and pattern of the stone. There are types of natural stone that can not be polished.
Polished surface is used for making marble and granite floors inside the room, countertops, bar counters, details for fireplaces, stained glass windows, etc., etc.It is not recommended to use a polished surface on the steps of the input group, as this is injurious.
3. Honed - uniformly - rough surface with traces of processing, obtained only when grinding the surface of the product after sawing, with roughness of the relief up to 0.5 mm high. The pattern, color and structure of the stone are manifested in this case weakly, and the overall background of the material becomes lighter. The honed texture is used for granite external surfaces of a large area.
4. Fine honed - treatment with thinner abrasives. Smooth matte surface with no visible traces of abrasive tools with a pronounced pattern of stone. It is used with both granite and marble.
4. Flammed - under the influence of a high-temperature gas jet. The surface of the stone is roughened, with traces of peeling and a well-defined structure. From heating the grains of the stone exfoliate, burn the top layer and burn out soft particles. Granite, for example, becomes non-slippery, like asphalt. At the same time, the color of the stone tarnishes and turns out to be lighter with a gray tinge. This problem can easily be solved with the help of special impregnations. After impregnation, the color of the stone will be saturated. The difference in heights on the surface with this treatment is up to 5 mm.
5. Bouchard - is formed by impact on the surface of the stone with hard-alloy tools. The surface is evenly rough, while the unevenness of the relief should not exceed 5 mm.
6. Sandblusted - when the surface is treated with a high-pressure air jet with the addition of fine abrasive or sand. The surface of the stone has a uniform undulating roughness.
7. Waterblusted - when treated with a high pressure water jet. The surface of the stone has a uniform undulating fine roughness.
8. Rockface - rough roughness of the stone is obtained as a result of chipping large pieces from the surface to be treated, forming a natural cleavage simulating a natural split of the rock with chaotic depressions and mounds, without traces of tools. Distinguish the rock of machine processing and manual."Rockface" is used, as a rule, in the stylobates of large and monumental buildings, emphasizes the massiveness, strength of the main structure, its connection with the surrounding landscape. The texture of the "Rockface" is formed on relatively massive elements with a thickness of at least 100 - 150 mm.
9. Acided - A stone item is placed in an acid that corrodes the soft parts of the stone. Recently, a template is applied to the surface and the surface is etched on top. Further, the acid is washed off with a jet of water and the surface turns out to be especially intricate and unusual. An expensive way of processing, mainly marble.
10. Natural - is formed in the production of roof slate. Thick blanks with the help of a tool are split and after that they are already cut to size.
11. Antik - aged texture - by surface treatment with brushes and abrasive blends. Brushes eat away soft parts of a stone, then abrasives grind. On the surface there are channels and hollows, imitating the old stone. Such processing gives an excellent opportunity to harmoniously combine the interior design of the house with landscape design, withstood them in a single style. Surfaces finished with antique, very pleasant to the touch and even with strong moisture remain non-slip, which is very important when facing bathrooms, saunas, swimming pools. Such a stone is unpretentious in exploitation, over the years, reverting, everything becomes "more ancient" and nobler. It is used mainly for marble.
12. Crack  - The texture formed after the split of the stone along the line of least resistance.A typical example is granite paving stones.
