Sandstone is a classic sedimentary rock comprising an aggregate of sand-sized (0.06–2.0-mm) fragments of minerals, rocks or fossils held together by a mineral cement. Actually, sandstone forms when sand is buried under successive layers of sediment. During burial the sand is compacted and a binding agent such as quartz, calcite or iron oxide is precipitated from ground water which moves through passageways between grains to create Sandstone.


The physical properties of sandstone are :

Mineralogy
A wide variety of rock fragments with up to 75% quartz grains .

Occurrence
Associated with most other sedimentary rock types .

Water Absorption
The capacity of water absorption is not more than 1.0%

Texture
Medium-grained; may range widely in degrees of grain sorting and shape


Structure
Bedding is often apparent along with sedimentary structures and fossils

Hardness
Lies between 6 to 7 on Moh's Scale Density 2.32 to 2.42 Kg/m3

Color
Sandstone is available in many colors – red, green, yellow, pink, gray and white. The reason for the variation in colors being the change in the percentage of constituent and the binding material.

Porosity
The porosity of sandstone is almost negligible. Thus sandstone is almost impermeable.

Compressive Strength
Varies from 365 to 460 Kg/m2
