You can polish it and thus make it look and feel like new at any time in its life.
Stone building materials properties.
A dimension stone is a building stone that is often.
Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30 40.
There is a great advantage to stone that is almost unique to floor finishes.
The stone lasts for example in the form of slate roofing for over 90 years.
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.
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.
Being dry stones allow more crushing strength than when wet.
Table given below shows the crushing strength of various stones.
Stone is a great floor finish and is affordable in many countries.
Resistance to decay strength and.
The reaction of water with material of stone.
Be it igneous metamorphic or sedimentary a building stone is chosen for its use durability attractiveness economy or other properties as desired.
Of durability attractiveness and economy.
Extraction requires only a small energy expenditure.
Italy and india are both known for the variety and quality of stone they produce.
Due to non uniformity of the material usually a factor of safety of 10 is used to find the permissible stress in a stone.
Stone is said to be workable when the work involved in stone working such as cutting dressing shaping is economical and easy to conduct.
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.
They have been used as building material since very early period of our civilization.
The more compact grained and heavier a stone the harder it is.
0 075 to 0 09 x 10 3.
Cost is an important consideration in selecting a building material.
Proximity of the quarry to building site brings down the cost of transportation and hence the cost of stones comes down.
Properties of building materials.
Which are discussed below.
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.
A building stone is chosen for its properties.
When natural stone is used as a building material a synergy is developed between the mason and the stone.
Some of the common building stones are granite basalt slate gneiss etc.
For a material to be considered as building material it should have required engineering properties suitable for construction works.
These properties of building materials are responsible for its quality and capacity and helps to decide applications of these material.
