Stone is also one of our common materials, so the application of stone is very common in our daily construction life. It is also one of the more important raw materials, and has played a great role in construction, road, bridge construction and so on. So, what are the characteristics of stone? Next, let's take a look with the editor of FABULOUS Group.

　　processability

　　The mining, sawing, grinding and polishing of stone is itself a process of resisting the action of external mechanical forces. The mineral deposits are easy to process such as low hardness, single composition, uniform structure and structure. Yes, you can only get used to rock with a certain strength. For example, the diamond structure saw is suitable for sawing marble, and the ZBQ sand saw is not good for sawing the stone with strong compression resistance. Different mineral deposits also have an effect on the uneven gloss. Dark mineral deposits are easy to polish, and lighter ones are more difficult. The difficulty of polishing is also related to the chemical composition. For example, in the original Ministry of TC79-92 Natural Marble Building Slab Standard, marbles with different compositions have different requirements for mirror gloss. Therefore, based on the mineral composition and chemical composition, it can be roughly known whether the gloss of the processed product has reached the requirement. Different chemical compositions have to choose different grinding heads in this article.

　　durability

　　It is desirable for any building to be used for a long time, and for the facing stone, it is also required to maintain its beauty for a long time. Therefore, it must have certain properties such as weathering resistance, frost resistance, and abrasion resistance, and the quality of these properties is related to the water absorption and porosity in the stone. Certain metal sulfides, such as pyrite, are easily oxidized into limonite or ferrous sulfate in the atmosphere, thereby reducing the strength and beauty of the stone. Therefore, the determination of mineral composition is also very important to understand the durability of stone. Radioactive elements are directly related to human health, especially stone used for interior decoration, and there must be strict restrictions on its radioactivity attempts.

　　usability

　　Any stone on any building, any piece of stone on each building, must have a certain degree of mechanical, such as compression strength, bending strength, and mineral composition, structural composition, structural structure, water saturation, etc., such as compression The strength of quartz and feldspar is higher than that of calcite and dolomite, so granite is generally higher in compressive strength than marble. Granite and marble themselves have different mechanical strengths due to their different compositions. Granite is generally higher than gabbro. The same kind of rock has different structures and different compressive strengths. For example, the fine-grained stone is higher than the coarse-grained structure. Higher than unequal grains. The acid and alkali resistance of stone is closely related to the chemical composition. Generally speaking, the content of SiO2 is high and the acid resistance is good, while the content of CaO and MgO is high and the alkali resistance is good.
