What is the Difference of Sandstone and Granite for Paving Slabs
- 16 Jun, 2019
Granite is naturally igneous rock formed of crystallized quartz and orthoclase, granite paving slabs usually are sawn by machines using high-density granite block, it is very difficult to split and cut because there are not layer in granite rock materials. The development of modern technology including gang saw and flamed machines to let granite as slabs textured as a possibility.
Granite paving slabs are not easy to split, so it is good hard wearing.
Sandstone is sedimentary rock, usually, quartz sand, cemented by silica, iron oxide, or calcium carbonate.
Sedimentary sandstone which has a natural cleft in the block. The clefts are opened manually using chisel and hammer, such as Kandla grey sandstone, Rippon buff sandstone, Autumn brown sandstone, and Raj green sandstone. The most of Indian sandstone materials are sedimentary sandstones, the more suitable finished face are natural split; If honed fished (smooth sandstone), the surface is easy to crack and chip scratch. Our stone experts do not recommend that the above sandstone materials be made into smooth sandstone paving slabs.
Solid blocks of sandstone which have to be cut on gang saw or circular saws similar to granite processing. The example of this type of sandstone is Rainbow and Teakwood. It can be sawn and honed, named as smooth sandstone paving.
