Crushing Resistance - an overview ScienceDirect Topics

The crushing resistance of SSA can provide an indication of its strength as an aggregate component and has been assessed, though only to a limited extent, using the 10% fines test, which measures the force needed to crush the material to the extent that 10% of the particles pass the 0.063-mm sieve, though this procedure is not strictly ...
