Morphological Characteristics Of Granite

Granite has a hard and dense texture, high strength, weathering resistance, corrosion resistance, abrasion resistance, low water absorption, and its beautiful color can be stored for more than a hundred years. It is a good material for construction, but it is not heat resistant. Granite stone is divided into different grades according to factors such as color, pattern, luster, structure and material. The Mineral Bureau of Taiwan's Ministry of Economic Affairs divides granite into six types: black, brown, green, off-white, light red and dark red. Although granite is a good material for construction, granite in some areas will overflow with radon, a natural radioactive gas. Radon can cause lung cancer. 13% of lung cancer deaths in Hong Kong are caused by excessive radon gas.
