Smith test is used to find out the compressive strength of stone.

Right answer is A.

Smith test is used to find the presence of soluble matter of stone.

What is smith's test?

Yes, the answer is right A.

Smith test used to find mud substance in stone.

Acid test if sandstone consis caco3, to find how much it in sandstone.

Tests on stone (Strength and Durability Tests).

Acid test (presence of calcium carbonate in building stone. If the edges are broken and powder is formed on the surface, it indicates the presence of calcium carbonate.

Attrition test ( (his test is done to find out the rate of wear of stones, which are used in road construction. The results of the test indicate the resisting power of stones against the grinding action under traffic. ).

Crushing test.
Crystalline test (Crystallization of CaSO4 in pores of stone causes decay of stone due to weathering).

Freezing and thawing test.

Hardness Test (Coefficient of hardness = 20 " (Loss of weight in gm/3).

Impact test (For determining the toughness of stone, it is subjected to impact test in a Page Impact Test Machine).

Smith's Test (Presence of earthy matter will convert the clear water into dirty water. If water remains clear, stone will be durable and free from any soluble matter).
