Oct 03, 2019 The crushed aggregate sample which is finer than 2.36 mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the 2.36m IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the ten
After 15 blows, the crushed aggregates were sieved through a 2.36 mm sieve and the AIV was determined using the following equation 2 0 AIV 100 W
The results obtained show that ACV value for aggregates are 25.04%, 22.70%, 36.13%,and 37.89% for crushed granite, slag , hoggin (all-in aggregate), and
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.
