The characteristics of granite

The compact structure, high compressive strength, bibulous rate is low. Low surface hardness. Good chemical stability. Strong durability. But it has poor fire resistance.

The granite is fine grain, medium grain, coarse grain granular structure, or porphyritic structure, the particles are uniform and fine, the gap is small(porosity is generally 0.3%~0.7%), water absorption rate isn’t high (water absorption rate is generally 0.15%~0.46%), has good forst resistance.

The granite has high hardness,it mohs hardness is about 6, the density of granite in 2.63g/cm3 to 2.75g/cm3, the compression strength in 100 to 300Mpa,among them, the compression strength of fine-granite can be reached more than 300Mpa, the bending strength is generally in 10 to 30 Mpa.

Granite is often produced in the form of rock base, rock strains, rock blocks, and controlled by regional geotectonics. The general scale is relatively large, and the distribution is also relatively wide, so the mining is convenient, easy to produce aniseed, and the joint development is regular, which is conducive to the mining of stone with regular shape.The granite has a high waste rate and can be processed in various ways. The plate can be put together well.Granite is not easy to weathering, can be used as outdoor decorative stone.Granite texture grain uniform, although the color is given priority to with light, but also very rich red, white, yellow, green, black, purple, brown, beige, blue and so on, and its color relative change is not big, suitable for the use of a large area.
