It is the bulk aggregate crushing strength which is determined. As stated above, usually aggregate is considered ten times stronger than crushing strength of concrete, but some particles break also and influence its strength. 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 .
