Granite is a kind of widely distributed rock, which occurs in all geological ages. The forms are mostly batholith, rock stock, rock bell, etc

granite characteristics

as we all know, granite is beautiful, durable and very hard. This is due to the dense structure of granite, which has high compressive strength, low water absorption, large surface hardness, good chemical stability, strong durability, but poor fire resistance

granite has fine, medium and coarse granular structure, or porphyritic structure. Its particles are uniform and fine, with small gaps (porosity is generally 0.3% - 0.7%), and its water absorption is not high (water absorption is generally 0.15% - 0.46%), which has good frost resistance

granite has a high waste rate, can be processed in various ways, and the plate can be spliced well. Granite is not easy to be weathered and can be used as outdoor decorative stone. The texture and lines of granite are uniform. Although the color is mainly light, it is also very rich, including red, white, yellow, green, black, purple, brown, beige, blue, etc. and its color changes little, which is suitable for large-scale use

The general price of granite stones is between 80 yuan and 500 yuan

hazards of granite

in recent years, granite has been widely used in the construction industry and home furnishings. Does granite have harm and impact on human body? The answer is yes, because granite will have slight radiation, and there are different degrees of radiation according to different materials, so people had better make clear its material and radiation when buying and using granite, so as to make home life more healthy. In addition, granite in some areas will overflow radon, a natural radioactive gas. Radon can cause people to suffer from lung cancer. 13% of lung cancer deaths in Hong Kong are caused by excessive radon

the above brief introduction about the types of granite, the price of granite stone and the harm of granite is here. I hope it can help you.
