Marmura vs Granit | Comparatie intre materiale

Don't click here - https://bit.ly/3eiUDXt Origin Granite is a volcanic rock that comes from the cooling of deep magmas and solidifies by slow cooling in the cracks of the crust. This sometimes has a diameter of several hundred kilometers. Marble is a metamorphic rock, formed as a result of the changes that limestone undergoes, after a very high temperature or pressure is applied to it. Composition Granite is composed of feldspar, quartz and dark minerals such as mica or amphiboles. It is part of the class of siliceous rocks. Marble is mainly composed of recrystallized calcite. Its place is in the category of calcareous rocks. Hardness For this comparison we use the Mohs scale, which measures hardness by scratch resistance. We consider level 1 attached to talc (soft) and level 10 for diamond (hardest), so granite has a hardness between 6 and 7, and marble between 3 and 4, each depending on the variety. Mechanical properties Granite is very resistant to compression, bending and impacts. Marble has weaker values ​​to mechanical actions performed on it. Temperature resistance All rocks are classified as non-flammable. Freeze-thaw cycles do not influence the behavior of natural stone slabs. Granite is a volcanic rock that is extremely resistant to very high temperatures. Abrasion resistance Granite has high resistance to abrasion and does not change its appearance through friction. Marble has medium resistance, its appearance can be affected over time. Stain resistance Both types of rocks are resistant to water, organic stains (coffee, tea, animal waste, etc.), grease (oil, grease), efflorescence, adhesive and grout residue. Most varieties of granite resist corrosive stains well (food acids, commercial detergents, cosmetic substances) while marble is sensitive to attack by corrosive agents, changing its appearance. Appearance and color The colors brought into feldspar granite are shades of white, blue, green and red. While quartz brings those of yellow, pink, brown and black. Marble contains pure calcium carbonate, to which various minerals are added that bring different shades of color (red from iron, brown from manganese). Marble is most often found in colors such as white, gray, gray, cream, black, red, green, a series of varieties with significant veins. Costs The price of granite starts from 85 lei/sqm and can reach 220 lei/sqm. The price of marble starts from 77 lei/sqm and can reach 1300 lei/sqm for special pieces, namely luxury slabs. Advantages A significant benefit of these materials and natural stone in general is the fact that they can be restored and brought back to their original appearance, if they have been stained or damaged, even after decades. Destination: Granite is recommended for use in heavier environments with intense traffic: public spaces, pedestrian alleys, parking lots, steps or kitchen countertops. Marble is used in spaces with lower traffic: bathrooms, living rooms, kitchens, fences, terraces, facades, complex projects and monuments. Conclusions: If granite wins points in terms of resistance, marble is superior in terms of the variety of colors and appearance, do not let this data make you think that marble is a less durable material, some of the most majestic projects in the world are built of marble and look extraordinary after hundreds of years.
