Aggregate Crushing Value Test – Determine Aggregate

May 17, 2019 Concept and significance of the Aggregate crushing value test. The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.

Effect Of Aggregates On The Properties Of Concrete

The crushing strength test discussed above has been found insensitive to the variation in strength of weaker aggregates. Therefore when such aggregates are tested by this method, they do not give true picture, because they get crushed before the full load of 40 tonne has been applied and get compacted causing the plunger to jam.
