Aggregate Crushing Value (ACV) The aggregate Impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. With aggregate of aggregate impact value higher than 30 the result may be anomalous.

Aggregate Crushing Value BS 812-110 and, Determination of Aggregate Crushing Value, The crushed aggregate will be carefully removed from the cylinder over [More] Sieve analysis Wikipedia, the free encyclopedia A gradation test is performed on a sample of aggregate in a laboratory A typical sieve analysis involves a nested.

The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30% or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source: IS 2386 (Part 4):1963)
