• Testing Of Stones

    The crushing strength of stones varies in the range of 15100 N/mm 2. Transverse Strength Test (IS: 1121 (Part II)): To test stone for transverse strength, specimen pieces are made in the form of blocks 200 × 50 × 50 mm. These are tested in saturated and dry conditions similar to as explained in the compressive strength test.
