Therefore aggregate to be used in cement concrete should not be weaker than the strength of hardened cement paste Determination of Crushing Strength of Aggregate Material for the standard crushing test should pass through 12 5 mm I S sieve and retained on 10 mm I S sieve The aggregate shall be thoroughly sieved on the above sieves before test.
Crusher type Compression type sec ondary crushers such as cone crushers squeeze rock until it breaks When used with some feed rock types cone crushers produce large amounts of flat and elongat ed particles In impact crushers the feed rock shatters as it collides with revolving fixed blow bars breaker plates or other particles of rock.
