Granite type and properties

Granite is a kind of magma below the surface condensation is igneous rock formation, the main ingredient is feldspar and quartz. Not easily weathered granite, color beautiful, colour and lustre appearance can keep more than one hundred years, because of its high hardness, wear resistance, in addition to used as advanced architectural decoration engineering, the hall ground, still the first choice for outdoor sculpture. Below small make up take you to know about the granite type:

1, according to the nature of the division

Biotite granite:

There are many color, biotite granite is one of the most widely used in construction of granite. It is the hardest of all the granite, applies no matter indoor or outdoor.

Talc granite:

Talc granite is one of the most known form of granite, because it can't very well to resist the forces of nature (wind, rain). This makes it less suitable for as a floor, mesa and outdoor use, only for decorative purposes.

Electric granite:

Electrical granite color variety, in addition to colorless and white, it is extremely rare. The granite type is the ideal place for don't have a lot of traffic, because it is all types of soft.

2, in accordance with the quantities of mineral species

According to the types of minerals can be divided into: granite black granite, white mica granite, Angle of flash granite, mica granite, etc.

3, according to the structure

In granite structure division, can be divided into: fine grained granite, medium grained granite, coarse grain granite, porphyritic granite, porphyritic granite, geode granite gneissic granite and black sands granite, etc.

4, in accordance with the quantities of the accessory mineral division

Granite, in accordance with the quantities of the accessory minerals can be divided into: including cassiterite, containing niobium ore granite, containing beryllium granites, lithium mica granite, tourmaline granite, etc.

Gold granite, gold of good quality, surface finish, high corrosion resistance to acid and alkali resistance, hardness, density, high iron content, no radioactive, nobility, colour, a kind of yellow grey, spreading ash pitting, and design and color is more yellow so called gold hemp. Gold for shandong's most famous. Stone categories: Granite (Granite), commonly known as China's gold.

Granite structure compact, hard, good acid and alkali resistance, weather resistance, can be in outdoor use for a long time. Characteristics of granite advantages include high load bearing, compressive ability, and good grinding ductility, easy cutting, shaping, can create a big plate of sheet etc., can be made into a variety of surface effect, polishing, inferior smooth, fine grinding, fire, water knife handle, sandblasting, etc. Commonly used in the ground, the steps, the place such as base, footfall, eaves, usually for indoor metope, ground, the adornment of the cylinder, etc.
