Impact of mechanical resistance of aggregate on
This aggregate feature is considered by testing its crushing strength, and the measure is the aggregate crushing value (ACV) [15]. Therefore, this indicator can be used for auxiliary and comparative estimation of concrete deformation properties. Testing the strength or elastic modulus of aggregate is not so easy, and the modulus of elasticity ...

The percentage of the crushed aggregates passing through the 2.36 mm sieve was determined as the aggregate crushing value (ACV). In order to investigate the particle distribution after the static ACVT, a full sieve analysis of the crushed aggregate was carried out. In this case, sieves of 0.075 mm, 0.15 mm, 0.3 mm, 0.6 mm, 1.18 mm, 2.36 mm, 4. ...

7 Different Types of Tests on Aggregates (Coarse)
Strength tests, such as the aggregate crushing value (ACV) and aggregate impact value (AIV), assess the aggregate's ability to withstand stresses. Typical ACV limits are 30% for concrete wearing surfaces and 45% for other concrete applications, while AIV limits range from 20% to 30% depending on the desired concrete strength.
