Aggregate Crushing Value Test – Determine Aggregate Crushing …
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.

Aggregate impact
Aggregate impact refers to the combined or cumulative effect of individual actions or events when assessed as a whole. In the context of legal analysis, particularly with the substantial effects test, it considers how seemingly minor activities can collectively influence interstate commerce, thereby justifying federal regulation. This principle emphasizes that while individual instances may be ...

Impact Value of Aggregate procedure, Limits
The impact value of aggregate measures how well a material can resist sudden, strong resistance, as aggregates with higher impact values are taken into consideration as much less durable and more liable to cracking beneath sudden masses, which may additionally affect the first-class of production. and Also, may affect sturdiness.
