Explanation: Crushing test: This test is carried out to assess the strength of coarse aggregate when a compressive load is gradually applied.; Aggregate crushing value = (W 2 /W 1) × 100 where, W 1 = Total weight of the dry sample . W 2 = weight of material passing through 2.36 mm IS sieve. The aggregate crushing value for the surface course should be within 30% and …
Principles of Mechanical Crushing
•The entire chamber is utilized for crushing. •The rocks falls/slides through the chamber until they are crushed directly between the concave and mantle. •The rocks are crushed in one strike which yields big forces •Most of the crushing in the lower part of the chamber. Feeding: Choke feeding yields more inter particular crushing
