Mechanical Properties of Aggregate

 · Greater is the aggregate crushing value, softer is the aggregate sample and vice versa. This is suggestive of the fact that the resistance of aggregates to crushing is less. Therefore, the strength of such a sample is also less. Aggregates having relatively less ACV can be used in wearing surfaces of pavements. 2)Hardness

Testing of Building Stones

They are tested in crushing test machine with loading N/mm 2 per minute. 3. Transverse strength test. A specimen of the stone whose length is ten times its depth is placed on wedgeshaped supports near its ends. A vertical load applied at the centre is gradually increased until failure occurs. The transverse strength, called the modulus of rupture, in MPa is computed as .
