· 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.
Bulking of Sand Test
Test Procedure. Take the sample sand and fill the measuring cylinder up to 200 ml. To make the necessary correction use the steel rule but don't compact the sand. Transfer that sample to a container. Refill the measuring cylinder with 100ml water. Now refill the sand into measuring cylinder and stir it well with the help of steel rod.

AGGREGATE CRUSHING VALUE
AGGREGATE 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.
