Sandstone from China, China Yellow Sandstone Slabs & Tiles

Sandstone is a sedimentary rock concise. From sand differs by the presence of a binder, which is very diverse. The main materials ska?otwórczymi sandstones are quartz, mica, feldspar, arkozy and greywacke.
sandstone color varies depending on the mineral composition: iron compounds provide the color yellow, brown or red. Organic substances stain dark gray to black. Galukonit sandstone stained green.
Most occur in nature quartz sandstones. Sandstone quartize or bonded silica have an average compressive strength, are compact and water-resistant. However, the main technical characteristics of sandstones from different regions of the world vary greatly:
Density: 1,80-2,70 g/cm3, compressive strength 10-140 MPa, nasi?kalno?? weight of 0.5-15%.
Sandstone is mined in China, mainly in the provinces of Yunnan, Sichuan, Shandong, Henan.
Average compressive strength is 70-80MPa (the provinces of Yunnan, Sichuan, Henan) to 120MPa in Shandong province. Water absorption 1-3% by weight.
Sandstone from China is used as a decorative plate or elevation, and as a sculptural material. Sandstone can polish and grind. most common colors of sandstone in China are: yellow, red, purple, gray, green.
