Granite is mainly composed of minerals such as quartz, feldspar and mica. It has the characteristics of dense structure, high compressive strength, low water absorption, large surface hardness, good chemical stability and strong durability.
The characteristics of granite are mainly reflected in physical properties, chemical properties and mechanical properties. Granite is mainly composed of minerals such as quartz, feldspar and mica. These minerals have high hardness, making granite have high wear resistance and durability. At the same time, granite has a high density, a hard texture, and is not easily weathered and eroded. In addition, granite also has good thermal conductivity and sound insulation. The chemical components of granite are mainly silica, alumina and iron oxide, which make granite have good acid resistance and alkali resistance. Under normal environments, granite is not susceptible to chemical corrosion and biological erosion, so it can maintain stability and aesthetics for a long time. The mechanical properties of granite are mainly reflected in their compressive resistance, tensile resistance and shear resistance. Because the mineral particles of granite are large and closely bonded to each other, their compressive strength is very high, reaching more than 3000MPa. At the same time, granite has high tensile and shear strength, and is not prone to cracking and deformation. In addition, granite has good seismic resistance and can remain stable in natural disasters such as earthquakes.
