## Strength and stiffness of compacted crushed concrete aggregate

crushing plants is usually around 40 mm, most of the previous TC tests used sieved materials having smaller D max values. Besides, the compressive strength of original concrete and the TC strength of compacted concrete aggregate used to produce the original concrete were both unknown. In view of the above, more systematically, the following four series of consolidatedAggregate Crushing Value Test - Significance & Test,,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 crushing value of aggregate = (W2/W1) x 100. Lab ReportAGGREGATE CRUSHING VALUE,The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. 2.Apparatus Required Fig. 1: Balance Balance should beAggregate crushing strength test - slideshare.net,30/12/2018· Aggregate crushing strength test 1.
