Aggregate crushing test
Aggregate crushing test is done to find out the strength of aggregate which is the fundamental and essential components of concrete, flexible pavements, etc. More than 70 to 80 per cent of the volume of concrete is aggregate. Aggregates are a very important component of concrete, so the quality really matters when it comes to aggregates.

Properties of aggregates- Physical properties, Chemical
1) Strength. Strength of the aggregates simply means compressive or crushing strength of the aggregate. It is represented by aggregate crushing value. ACV is the quantified resistance provided by aggregates to the progressively applied compressive/crushing loads. This is generally determined for coarse aggregates.

Effect of Aggregates on the Properties of Concrete
The bond strength depends upon the strength of cement paste and on the properties of aggregate surface as well. Bond strength is found to increase with the age of concrete. 2. Crushing Strength of Aggregate: The compressive strength of concrete cannot exceed that of the aggregate used therein.

Greater is the aggregate crushing value, softer is the aggregate sample and vice versa. This is suggestive of the fact that the resistance of aggregates to crushing is less. Therefore, the strength of such a sample is also less. Aggregates having relatively less ACV can be used in wearing surfaces of pavements. 2)Hardness
