The construction projects are shifting towards exploring greener options. The idea of greener construction has been for ages. The stones ideal for greener construction projects are natural stones. It has been a clear and concise choice of builders and homeowners, as the natural stone has proven its excellence right from humble homes to magnificent monuments. 


Why are Natural Stones called a green material? 

Natural stones are extracted naturally and have no chemicals involved. So the release of harmful VOCs is not possible. Natural stones have strong resistance towards heat, fire, temperature fluctuations, water and moisture, and microbial growth. Various types of natural stones are used commonly. These are marble, granite, limestone, sandstone, slate and there are many more on the list. 


Here is a detailed analysis of some common types. 

Marble 

Marble is a metamorphic rock that forms in extreme pressure and heat for a long time. Marble was initially available in white color but now the domain has expanded and other colors are included. The color range involves pink, red, and gold. The natural stone exhibits elegance and purity. Commonly used in exterior cladding, landscaping, interior surfaces, and flooring. The stone known for its unmatchable beauty is susceptible to corrosion and staining. Hence, it is avoided as a kitchen countertop as its surface can get corroded and stained from the acids and chemicals, even if it's properly sealed. 

Granite

Granite is formed deep below the earth's crust from solidified magma. It is a pyrogenic rock. The constituents of the natural stone are feldspar, quartz, and mica. The minerals form a veining and sparkly detail on the granite surface. Granite is widely used for interior décor. The common areas include countertops, cladding, flooring, walls, landscaping, and paving. The natural stone has high density, strength, and hardness to withstand as kitchen countertops. A metamorphic rock called gneiss is considered a duplicate of granite. It looks similar to granite but has a denser mineral grains look. 

Limestone

Limestone is formed by the dead remains of the organisms compressed for years under pressure. It is a sedimentary rock. Limestone consists of calcium carbonate, magnesium, silica, and other important minerals. The natural stone is widely installed as exterior cladding, paving, and interior surfaces like flooring and landscaping. The classic colors of limestone include white, grey, beige, and pink. Limestone is a non-crystalline stone and is highly susceptible to chemicals. Therefore, it is not ideal for outdoor purposes as it can get easily corroded. 

Sandstone

The sedimentary rock consists of sand, feldspar, and pieces of quartz. The stone is durable and resistant to major issues. Minerals like calcium carbonate, silica, and iron oxide are also present. The rock provides a sleek and elegant look to the place installed. 


Conclusion

Natural stones are obtained through quarrying and not through mining. Thus, extraction does not cause environmental concerns like mining. The stone is a natural product and does not discharge carcinogenic substances. The entire industry has revolutionized to generate stone with efficacy and minimum environmental effect.
