Stone Building Materials Properties

Extraction requires only a small energy expenditure.

Stone building materials properties.

The stone lasts for example in the form of slate roofing for over 90 years. When natural stone is used as a building material a synergy is developed between the mason and the stone. Being dry stones allow more crushing strength than when wet. Table given below shows the crushing strength of various stones.

The more compact grained and heavier a stone the harder it is. 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. Properties of building materials. 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.

It is the ability of a stone to endure and maintain its essential and distinctive characteristics i e. These properties of building materials are responsible for its quality and capacity and helps to decide applications of these material. Resistance to decay strength and. Be it igneous metamorphic or sedimentary a building stone is chosen for its use durability attractiveness economy or other properties as desired.

They have been used as building material since very early period of our civilization. A dimension stone is a building stone that is often. There is a great advantage to stone that is almost unique to floor finishes. Of durability attractiveness and economy.

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. Due to non uniformity of the material usually a factor of safety of 10 is used to find the permissible stress in a stone. Natural stone has an indelible imprint on the long history of mankind. 0 075 to 0 09 x 10 3.

Which are discussed below. Stone is said to be workable when the work involved in stone working such as cutting dressing shaping is economical and easy to conduct. Stone is a great floor finish and is affordable in many countries. In the past few years this building material experienced a renaissance not least because of its ecological properties.

Cost is an important consideration in selecting a building material. A building stone is chosen for its properties. For a material to be considered as building material it should have required engineering properties suitable for construction works. Some of the common building stones are granite basalt slate gneiss etc.

Proximity of the quarry to building site brings down the cost of transportation and hence the cost of stones comes down. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30 40. 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.
