Procedure for crushing strength of aggregate Before testing the aggregate should be in surface dry can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100degree Celcius The aggregates passing through 125mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength
Jun 27 2020 · The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS2386 Part 4 The aggregate crushing value provides 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 should be preferred
371 Cube Strength The following 28 days standard cured crushing strength concretes are specified for this Contract • 30 MPa minimum throughout except as noted otherwise in this Specification or on the drawings 372 Certified Supplier Except as expressly specified to the
For this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner This testing method is known as an aggregate crushing value test Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load
