- Aggregate Crushing Value Definition

Calculation of aggregate crushing value. The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2.36mm sieve) to the total weight of sample expressed in percentage. W1= Weigh of the total aggregates (Wa-We) W2= Weigh of aggregates passing through 2.36mm IS sieve.

The tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the ﬂexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality.

The definition of sandstone is described in Section 904.02. Slag Aggregates When slag is furnished as an alternate to natural aggregate, the payment is on a weight basis, adjustments must be made to compensate for the difference in specific gravity of the slag compared to the specific gravity of the natural aggregate.
