As per section 6.1: IS 1121-1974 (part IV)
- The shear strength of the test piece shall be calculated as follows
S = \(\frac{W}{2A}\)
Where S is shear strength (kg/cm2)
W is the total maximum load in kg indicated by the testing machine
A is the area of the center cross-section of the test piece (cm2). (Ref. sec 6.1; IS 1121 part IV-1974)
- The durability of the stone shall be expressed in percentage as a change in the weight of the specimen. (As per section 5.2, of IS 1126-1974)
