Get Priceaggregate 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.the crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.m 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.
Get Pricethe 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 aggregate used in road construction, should be strong enough to resist crushing under traffic wheel loads. If the aggregates are weak the stability of the pavement structure is likely to be adversely affected. the strength of coarse aggregates is assessed by aggregate crushing test.
Get PriceAn aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger. the specimen is then loaded via the plunger. the load crushes the aggregate to an extent depending on the crushing resistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing valueaggregate crushing value of coarse aggregate. note -the aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. with aggre- gate of aggregate crushing value or higher, the result may be anomalous, and in
