In the past few years this building material experienced a renaissance not least because of its ecological properties.
Stone building materials properties.
Hence even laterite can be used safely for a single storey building because in such structures expected load can hardly give a stress of 0 15 n mm 2.
Resistance to decay strength and.
The stones used for building construction should be hard durable tough and should be free from weathered soft patches of material cracks and other defects that are responsible for hellip.
Table given below shows the crushing strength of various stones.
There is a great advantage to stone that is almost unique to floor finishes.
Due to non uniformity of the material usually a factor of safety of 10 is used to find the permissible stress in a stone.
These properties of building materials are responsible for its quality and capacity and helps to decide applications of these material.
Some of the common building stones are granite basalt slate gneiss etc.
Stone is said to be workable when the work involved in stone working such as cutting dressing shaping is economical and easy to conduct.
Cost is an important consideration in selecting a building material.
It is the ability of a stone to endure and maintain its essential and distinctive characteristics i e.
Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30 40.
For a material to be considered as building material it should have required engineering properties suitable for construction works.
Many types of stones are available such as basalt marble limestone sandstone quartzite travertine slate gneiss laterite and granite which can be used as construction materials.
Which are discussed below.
Of durability attractiveness and economy.
You can polish it and thus make it look and feel like new at any time in its life.

Natural stone has an indelible imprint on the long history of mankind.
Natural stone is an imperfect medium that prompts the mason to listen to his intuition and act upon his experience to create an artful design.
Stone is a great floor finish and is affordable in many countries.
The reaction of water with material of stone.
Extraction requires only a small energy expenditure.
Proximity of the quarry to building site brings down the cost of transportation and hence the cost of stones comes down.
Italy and india are both known for the variety and quality of stone they produce.
The more compact grained and heavier a stone the harder it is.
When natural stone is used as a building material a synergy is developed between the mason and the stone.
A building stone is chosen for its properties.
0 075 to 0 09 x 10 3.
Being dry stones allow more crushing strength than when wet.
Be it igneous metamorphic or sedimentary a building stone is chosen for its use durability attractiveness economy or other properties as desired.
