The aggregate crushing value test is an important test of aggregates. It gives a numerical index of the strength of the aggregate and it is used for concrete in construction of roads and pavements. The aggregates have minimum crushing value are recommended for roads and pavements as it indicates a lower crushed fraction under load and would
Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results.
the aggregate crushing value. Aggregate crushing value W1 W2 100 A value less than 10 signi es an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates. Piston Load Sample Figure 221 Crushing test setup 22.3.2 Abrasion test
