  • Aggregate Crushing Value Test – Determine Aggregate

    · The ‘ aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregateThe aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) ADETERMINATION OF AGGREGATE CRUSHING VALUEAggregate Crushing Value and Its Test Procedure: One of the test in which concrete material can fail is due to crushing under compressive stress Aggregate crushing test is standardized by IS: 2386 partIV and used to verify the crushing strength of aggregates The aggregates should be oven dried, which can passes through 125mm and retained onHow to Find Aggregate Crushing Value and Its Test Procedure?
