What is the difference between quartzite sandstone and crushed granite?

Modern mining industry offers us various types of stone for construction and decoration. Some of them are crushed granite and quartzite sandstone. Both of these materials are in demand and have found their application. Today I will tell you what are the differences between these materials.

Quartzite sandstone is a natural stone of high strength, formed during the transformation of sandstone into quartzite. It consists of quartz crystals welded together. As a rule, quartzite sandstone is a fine-grained material.

Crushed stone is formed with the help of human mechanical impact on rocks (undermining) and further crushing of granite stone. The explosion produces pieces of different sizes. One-piece structures, such as curbs, are produced from large pieces, and small pieces are used in industrial, household, road construction. Granite crushed stone is mainly used for the production of concrete, which, with its help, acquires the highest strength properties. Small crumbs can be used for interior decoration, decorative items.

Quartzite sandstone very beautiful and has a special color and shine. Due to such aesthetic properties and a wide palette of colors, quartzite sandstone is widely used as finishing materials, for facing the facades of buildings, in landscape design, for the manufacture of artistic and architectural structures. Besides, quartzite sandstone has no radioactive background, that makes him absolutely safe and environmentally friendly for indoor use.

In terms of strength, these materials do not differ much - quartzite sandstone is not inferior to granite crushed stone. The density of quartzite sandstone and granite stone ranges from 2400 to 2650 kg / m3.

Both materials are durable and in demand. Despite similar strength characteristics, quartzite sandstone and granite crushed stone have a different composition. To obtain the final product of the desired fraction, quartzite sandstone is cut or cleaved, and crushed stone is crushed.

Advantages of quartzite stone: the material has the ability to mirror polish and has a low level of abrasion.

Advantages of crushed granite: high adhesion, good adhesion to binding materials, material resistance to periodic freezing and thawing (the number of cycles - up to 200 times).
