Jun 26, 2015 No single stone can satisfy all the below mentioned quality requirements. For example, strength and durability requirement contradicts ease of dressing requirement. Hence it is necessary that site engineer looks into the properties required for the intended work and selects the stone accordingly. Requirements of Good Building Stones The following are the quality requirements of
In this test, a sample of stone weighing about 0.50 to 1 N is taken. It is placed in a solution of hydrochloric acid having strength of one per cent and it is kept there for seven days. The solution is agitated at intervals. A good building stone maintains its sharp edges and keeps its surface free from powder at the end of this period.
For a good building stone, its specific gravity should the greater than a 1.5 b 1.7 c 2.2 d 2.7
Jun 28, 2018 Specific gravity The specific gravity of Building stone is directly proportional to its weight and strength. Hence the stones having higher specific gravity should not be used for dams, retaining walls, docks and harbours. Specific gravity of a good building stone lies between 2.4 to 2.8.
Jul 10, 2020 A good bldg stone should have sufficient crushing strength to withstand the load of superstructure. It should 1000 kgcm . HARDNESS, TOUGHNESS AND RESISTANCE TO ABRASION The stone to be used in stone pavements, as railway ballast or road metal must be sufficiently hard, tough, resistance to abrasion.
The specific gravity of good building stones should be between 2.4 and 2.8.
A good building stone must have good crushing strength the crushing strength of the stone varies from 150 to 1000 kgcm2. 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.
Strength is an important property to be looked into before selecting stone as building block. Indian standard code recommends, a minimum crushing strength of 3.5 Nmm2 for any building block.
Crushing Test On Building Stone. the crushing strength of the stone is determined in a compression machine.2.54cm long cylinder 2.54cm cube is tested. The minimum crushing strength of 700kgcm2 is desirable. No. Of specimen to be tested is three.
Crushing Strength Test of Stone. For conducting this test, a specimen of size 40 40 40 mm is prepared from parent stone. ... The solution is agitated at intervals. A good building stone maintains its sharp edges and keeps its surface intact. If edges are broken, and powder is formed on the surface, it indicates the presence of calcium ...
Strength is an important property to be looked into before selecting stone as a building block. Indian standard code recommends, a minimum crushing strength of 3.5 Nmm 2 for any building block. Table 1 shows the crushing strength of various stones. Due to the non-uniformity of the material, usually, a factor of safety of 10 is used to find the ...
Jul 20, 2018 Compressive strength test. This test is vital for evaluating the stones resistance to crushing loads. A wall stone has to bear the compressive load of the stones weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in. A ...
The safe working strength for piers, etc., should not exceed one-tenth of the crushing strength. Tables giving the crushing strength of many well-known stones and the safe working strength for stone masonry are given in the appendix. The method in which a stone is quarried sometimes has much to do with its strength.
Dec 15, 2014 Qualities of a good building stone Crushing strength For a good building stone, the crushing strength should be greater than l000kg per cm2. Appearance Good building stone should be a uniform colour, and free from clay holes, spots of other colour bands etc capable of preserving the colour for longtime.
