Acid Test on Building Stone This test is carried out to understand the presence of calcium carbonate in building stone. A sample of stone weighing about 50 to 100 gm is taken. It is placed in a solution of hydrophobic acid having strength of one percent and is kept there for seven days. Solution is agitated at intervals.

It has been found that in stones, transverse strength is generally 1/10 th to 1/20 th of their compressive strength values. Shear Strength of a stone is also not commonly determined except when the stone is to be used as a column. It has been observed that in important building stones the shear strength lies between 70-140 kg/cm 2. 3. Porosity:

So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.

The compressive strength of a stone determines its ability to withstand the weight of stacking on top of each other. A building stone’s compressive strength should be 60 to 200N/mm2. Location and composition determine a stone’s durability. The size, structure, and type of minerals in a stone make up its composition.
