Aggregate Crushing Value Test

The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value" should be determined ...

The P s value for U (0, 1) of 0 and 1 is 1.37 and 0.55, respectively. Even though the HC model predicted the mechanical response of sand at quasi-static strain rates accurately, Ciantia et al. used large particle comminution limits and only allowed particles larger than 0.55 × d 50 to break, which masked the PSD evolution in the simulation. The model also does not account for the confinement effect provided to …
