The strength of coarse aggregates is assessed by aggregates crushing test. the aggregate crushing value provider. a relative measure of resistance to crushing under a gradually applied compressive load. to achieve a high quality of pavement, aggregate possessing low aggregate crushing value The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected. procedure first of all, take the sample passing sieve inch and retained on sieve 38 inch.What is the difference between crushing value and impact value block products. as a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, what is the difference between crushing value and impact value block, quarry, aggregate, and different kinds of minerals.Aggregate crushing value w2 x 100 w1-w w2 weight of fraction passing through the appropriate sieve w1-w weight of surface dry sample. the mean of two result to nearest whole number is the aggregate crushing value. result the aggregate crushing value of the given sample aggregate crushing values for roads and pavement constructionDec 19, 2019 if the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregate. after performing the test, the crushed material is separated and calculated in terms of percentage of the original weight taken in the mould.Oct 01, 2016 the aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. also read crushing value test of aggregates. 13. impact value. the aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact.
