Sand Stone
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.
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 | 16-40 N/mm2
| | Water Absorption | 1.0 - 1.2 %
| | Porosity | Low to very low.
| | Weather Impact | Resistant
|
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.
| SiO2 | 95-97%
| | Iron (Fe2O3) | 0.5%-1.5%
| | 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%
|
They are highly resistant to acids, alkalies and thermal impact. Insolubility in acids and alkalies is about 97%.
Teakwood and Rainbow sandstones differ from above physical properties
| Hardness | 6 to 6.5 on Moh's Scale
| | Density | 2.07 to 2.11 Kg/cm3
| | Compressive Strength | 41 to 63 N/mm2
| | Modulus of Rupture | 7-11 N/mm2
| | Water Absorption | 8.0 - 11 %
| | Porosity | Comparatively Porous
| | Weather Impact | Resistant

Uses of Sandstone
- Manufacturing of plate glass, fine table glassware, and common glassware.
- Crushed in concrete and asphalt to fill in dike and jetty construction.
- Rough and weathered sandstone is used as fireplaces, walls, and walkways.
- As decorative stones.
- As bookends, clocks, paperweights, coaster, etc.
- As flooring or paving material.
- Load bearing masonry
- Sandstone slabs and sandstone tiles are used in cladding.
- In chemical industries as flooring, wall fixing and lining due to its acid and alkali resistant properties.
- It is ideal for carving and architectural uses as pillars, arches, garden furniture, fountains, landscaping products and stone arts & crafts.
- Sandstone blocks are used as foundations and stonewalls.
