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. Aggregate crushing value=( W2 / W1 ) × 100

Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load
Learn MoreThe load shall be released & the whole of the test sample shall be removed from the cylinder and sieve with 2.36mm IS Sieve. The passing sample shall be weighed ( W2, gms). Aggregate crushing Value = (W2/W1) x 100. Read more: Method Abrasion value test; Method of Impact value test; Method of ten Percent fine value of Coarse Aggregate
Learn MoreThe aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. Why to test Aggregate Crushing Value? The principal mechanical properties required in road stones are:
Learn MoreAggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67 (Impact Value)

Learn MoreThe aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low crushing value should be preferred. Lower crushing value means …
Learn MoreAggregate crushing value test step by step procedure ,the average crushing value in the different tests is the actual crushing value of aggregate. important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than then 10% finer aggregate is suggested to use. the aggregate whose crushing value is less than 30% can be used for

Learn MoreAggregate 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 …
Learn MoreMar 30, 2020 · 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 give a longer service life and a more …
