Requirements of Good Building Stones

Requirements of Good Building Stones

The good quality building stone must possess a number of characters for their efficient work in building and other structures. Some important characteristics are as follows:

Good Building Stone

1. A good building stone should have a pleasing and uniform colour and free from cracks, decay, clay holes, etc.


2. A good building stone should have an unstratified structure. Rocks with stratified nature will split up along the plane of stratification, if not properly placed.


3. A good building stone should be fine-grained because they are having good crushing strength as well as good texture.
4. The good building stones should be compact because these can resist more pressure.


5. A good building stone should be heavily weighted because the weight of stone indicates the porosity and density of the stone.


6. A good building stone should have less porosity because of lesser the porosity more the compactness or vice versa.


7. A good building stone should be durable. The durability of a stone depends upon the structural formation, chemical composition, cementing material and lower of resisting wear and tear.


8. A good building stone must have good crushing strength the crushing strength of the stone varies from 150 to 1000 kg/cm2.


9. A good building stone must be hard enough. A rock not scratched by a knife represents a hardness of 7 and if scratch with a fingernail represents a hardness of 2.


10. A good building stone should have the power to resist the wear and tear due to atmospheric actions.


11.  A good building stone should be readily workable. These should have the qualities to facilitate easy cutting, dressing i.e. bringing into the required shape and size.


12. A good building stone should not absorb the water more than 10% when immersed in water for 24 hours.


13. A good building stone should be fire resistance. Stones must maintain their strength and compactness when exposed in the fire.
14. A good building stone should be seasoned for 8 to 10 months before they can be used.


15. A good building stone should be tough. Toughness index 13 to 19 are considered as medium tough and stones with toughness index less than 13 are poor stones.


16. A good building stone should have a good texture. Fine-grained stones with homogeneous distribution look attractive and hence they are used for carving.
