The more the specific gravity of stone, the more heavier and stronger the stone is. Therefore stones having higher specific gravity values should be used for the construction of dams, retaining walls, docks and harbors. The specific gravity of good building stone is between 2.4 and 2.8. 6. Porosity and Absorption

Crushing test. The crushing strength of a stone is the maximum load it can withstand per unit area before failure. It is determined by dividing the maximum crushing load by the area of the stone's bearing face. To assess the crushing strength of stone, samples are cut into cubes measuring 40 x 40 x 40 mm.

If it is in between 14 and 17, the stone is said to be medium hardness. If it is less than 14, stone is said to be poor hardness and such stones are not fit for road work. If wear is more than 3%, the stone is not satisfactory. If it is equal to 3%, stone is just tolerable. For a good building stone, the wear should be equal to or less than3%.

If it is equal to 3 /c. the stone is just tolerable. For a good building stone, the wear should be equal to or less than 3%. Crushing strength: For a good structural stone, the crushing strength should be greater than 300 N/mm-. The approximate values of crushing strength of some of the stones are shown in Table 2.5 durability of stones.

1. Crushing Strength. For a good building, stone crushing strength should be more than 100 N/mm3 to bear the applied load. If the stone failed to bear this load then the stone can not use for the purpose of …

Requirements of a Good Building Stone. It should be hard, tough, sound, durable and should withstand wear and tear. It should have high crushing strength. A good building stone should not be affected by bad weather or polluted atmosphere. It should have uniform and pleasing colour. It should be fine grained, compact and crystalline in structure.

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 N/mm2 for any building block.

The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance …

Detailed Solution. It means to expose the stone in the open air for a period of 6 to 12 months. It removes quarry sap and makes the stone-hard and compact. A good building stone should not be porous because the porous stone is easily decomposable and get disintegrate. Hence porous stones are not suitable for construction or building …
