Jodhpur Fort & Umead Bhawan PalaceJodhpur sandstone know commanly as Chhittar is in many ways superior to other sandstones from other parts of India and as well globe.
 

Beside its inherent asesthetic appeal and attractiv appearances, its has more unique qualities like it is least affected by air, sunshine, rain and extreme weather conditions.
This stone further do not require surface treatment due to high silica content and work almost like granite when used in cladding.
 

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.


For thousands of years, sandstone from Jodhpur has been quarried and used in construction. It can be seen in form of archeological momuments strewn all around Jodhpur. the cenotaphs, architectural ruins.
Large scale quarrying done in 14 century in making of most maginificient fort of India, Mehrangarh Fort.
 

Properties of Sandstone:
Jodhpur sandstone is resistant to acid, alkali, salinity and thermal variance, which makes it suitable for constructing buildings, landscaping, paving, cladding, cobbles etc.
Due to so much strenght and properties its highly suitable for multi storied buildings, swimming pools, religious places of worship, seashore buildings and wide applications in extreme climate.

Jodhpur sandstone varies in texture and is fine to medium and even coarse grained, massive hard and compact at places and porus sometimes.
It is available is pink, brownish and reddish shades with beautifull natural grains and looks.

Nowdays, Tiles, slabes , cubes, cobbles, landscpaing stone are regularly available with blocks for up scale commercial usage.
While handcrafted or carving stone like pillars, designed, Jali and wide beautifull momumental replicas are being made for exteriors and interiors.

Physical Properties of Sandstone

Color
The color varies from red, green, yellow, gray and white. The variation is result of the binding material and its percentage constituent.

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

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

Porosity
The porosity varies from low to very low.

Compressive Strength
Varies from 365 to 460 Kg/m2

Chemical Properties of Sandstone
The chemical constitution of sandstone is the same as that of sand, the rock is thus composed essentially of quartz. The natural cementing material that binds the sand together as rock is usually composed of silica, calcium carbonate, or iron oxide. Chemically sandstone is very resistant Mono-Mineralic rock, with silica as the principal. The percentage of each constituents is as follows:

 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.
