How Long do Granite Headstones Last

For a long time, a lot of laymen for stone can only be separated from the color, what granite, marble, silly points are not clear, resulting in stone selection for Granite Headstone, there are many unprofessional problems. 

Compared with the nature of reinforced concrete and stone is more unstable, vulnerable to the influence of the external environment, its service life is relatively limited, vulnerable to external erosion and cracking resulting in internal steel corrosion damage, thus aggravating the speed of damage, resulting in a greatly reduced service life.  As well as other natural erosion and weathering effects, from historical experience, reinforced concrete structures are designed to have a long service life of no more than 100 years, generally 70 years, which is far less than the life of the existing ancient Granite Headstone.  

What's more, modern material design products can not reflect the local characteristics, based on the above reasons, the use of tombstone materials are better domestic granite, marble, etc., the same material used in ancient tombstones.

First, granites are igneous rocks, usually formed from volcanic materials such as magma.  And marble belongs to metamorphic rock, is in the high temperature and high pressure environment and the mixing of minerals, by the natural metamorphism of a stone into another stone.  Therefore, granite belongs to hard stone, its rock is hard and dense, and marble belongs to hard stone, usually has obvious patterns, mineral particles are also quite many, not only hardness than granite, but also not conducive to prominent tombstone itself inscriptions, carving patterns and other content, natural people choose granite more.  

Second, marble generally contains impurities, and it contains calcium carbonate by carbon dioxide in the atmosphere, carbide, the effect of moisture, also easy to weathering and dissolution, and make the surface soon lose its luster, so weak on the tombstone the outdoor stone carvings, and the nature of the granite due to not easily weathered metamorphic, appearance can keep more than one hundred years,  Therefore, it is used for wall foundation and exterior wall decoration, tombstone production, etc., which can better withstand wind and rain erosion.  

In addition, under normal circumstances people can distinguish with the naked eye marble and granite, marble pattern is rich, and change color, and a single granite design, generally are gray, white, no obvious pattern forming, thus, the former smooth delicate texture, texture rich, more artistic, more used for interior decoration, more popular with consumers;  The latter design is onefold, decorative is not strong, but because of its own hard, not easy to damage, more suitable for outdoor, so on the choice of tombstone, it is best to use granite, preserve longer.
