Requirements of Good Building Stones

The following are the necessities of fine building stones:
(i) Strength: The stone ought to be ready to resist the load drawing close it. Ordinarilly this can be not of primary concern since all stones ar having sensible strength. but just in case of huge structure, it's going to be necessary to see the strength.
(ii) Durability: Stones elect ought to be capable of resisting adverse effects of natural forces like wind, rain and warmth.
(iii) Hardness: The stone utilized in floors and pavements ought to be ready to resist abrasive forces caused by movement of men and materials over them.
(iv) Toughness: Building stones ought to be robust enough to sustain stresses developed thanks to vibrations. The vibrations is also thanks to the machinery mounted over them or thanks to the masses moving over them. The stone aggregates utilized in the road constructions ought to be robust.
(v) Specific Gravity: Heavier form of stones ought to be used for the development of dams, retentive walls, docks and harbours. the precise gravity of fine building stone is between two.4 and 2.8.
(vi) porousness and Absorption: Building stone shouldn't be porous. If it's porous rain water enters into the pour and reacts with stone and crumbles it. In higher altitudes, the state change of water in pores takes place and it results into the disintegration of the stone.
(vii) Dressing: Giving needed form to the stone is named dressing. It ought to be straightforward to decorate so the price of dressing is reduced. but the care ought to be taken so, this can be not be at the price of the desired strength and also the sturdiness.
(viii) Appearance: just in case of the stones to be used for face works, wherever look may be a primary demand, its color and skill to receive polish is a crucial issue.
(ix) Seasoning: sensible stones ought to be free from the quarry sap. soil stones shouldn't be used for six to twelve months when production. they're allowed to induce obviate quarry sap by the action of nature. This method of removing quarry sap is named seasoning.
(x) price: Cost is a crucial thought in choosing a artifact. Proximity of the quarry to putting together web site brings down the price of transportation and therefore the price of stones comes down.
However it's going to be noted that not one stone will satisfy all the necessities of an honest building stones, since one demand might contradict another. for instance, strength and sturdiness demand contradicts simple dressing demand. therefore it's necessary that web site engineer appearance into the properties needed for the inteded work and selects the stone.
