Explanation: Crushing strength or compressive strength of a stone is the load per unit area at which the stone starts cracking. It should be greater than 100 N/mm 2 to ensure sufficient strength for use in construction.
Strength . Ordinarily, the strength of a stone is not of primary importance, as very often the loads to which it is subjected in a structure are much below its permissible crushing strength. Durability . Stones should possess a natural durability to withstand the destructive effects of various agents continuously operating on them.

Crushing Strength Of Stone. The crushing strength of good building stone should be greater than the crushing value of coarse aggregate. It is the weight percentage of crushed material obtained when the aggregate bears the specified load under standardized conditions. The aggregate crushing value is the numerical index of aggregate strength. Learn More
Crushing strength: For a good building stone, the crushing strength should be greater than l000kg per cm2.9. Texture: A good building stone should have compact fine crystalline structure should be free from cavities, cracks or patches of stuff or loose material. Stone Mastic Asphalt.

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.
A good building stone must absorb less than 5% water and those stones that absorb more than 10% of water should be rejected. Sandstones should not absorb water more than 10%, 17% in case of limestones and 1% in granites of their volume when dipped for 3-4 hours. 9. Smith’s test.
