Take a look at some of the handpicked varieties of high quality sandstones from our huge collection.
Read More About Sandstones :
Sandstone is a sedimentary rock group which is mostly made up of tiny grains of quartz. Most sandstone is formed in oceans, lakes and rivers where tiny bits of rock and dirt settle to the bottom. Year after year, these layers of sand get buried under tons of more sand and dirt until it is turned into solid rock. Sandstone can be found in many colors.
Use of Marble :
- It is ideal for carving and architectural uses as pillars, arches, garden furniture, fountains, landscaping products and stone arts & crafts.
- Rough and weathered sandstone is used as fireplaces, walls, and walkways.
- In chemical industries as flooring, wall fixing and lining due to its acid and alkali resistant properties.
- Crushed in concrete and asphalt to fill in dike and jetty construction.
- As bookends, clocks, paperweights, coaster, etc.
- Sandstone blocks are used as foundations and stonewalls.
- Sandstone slabs and sandstone tiles are used in cladding.
Physical Properties of Sandstone :
Physically, they are very Hard, Compact, Fine grained, equi-granular homogeneous rocks of sedimentary nature (Sandstone)
|Color||Minor color tonal variations exist but within the tolerance limit.|
|Hardness||6.5 to 7 on Moh’s Scale|
|Density||2.3 to 2.4 Kg/cm3|
|Compressive Strength||90 to 140 N/mm2|
|Modulus of Rupture||16 to 40 N/mm2|
|Water Absorption||1.0 – 1.2 %|
|Porosity||Low to very low|
Note : Teakwood and Rainbow sandstones differ from above physical properties.
Chemical Properties of Sandstone :
Chemically they are very resistant Mono-Mineralic rocks, principally composed of silica. The other minor constituents vary from origin to origin.
|Fe2O3||0.5-1.50% (varies with variety)|
|Alumina (Al2O3)||1 to 1.5%|
|Soda (Na2O) & Potash (Kro)||Less then 1%|
|Lime (CaO)||Less then 0.5%|
|Magnesia (MgO)||Less then 0.5%|
|Loss On Ignition (LOI)||Less then 0.5%|
