Aggregates Crushing Value Test

Aggregate 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 on 10mm sieve

Sep 12 2015 · A test is standardized by IS 2386 partIV and used to determine the crushing strength of aggregates The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions See Fig1

Mar 31 2017 · Source Read full article at Aggregate Crushing Value test IMPACT TEST ON AGGREGATES Aggregate Impact Value test determines the Aggregate Impact Value AIV of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact Resistance of the aggregates to impact is termed as toughness

Jan 25 2018 · AGGREGATE CRUSHING VALUE TEST AIM To find Aggregate Crushing value of the given aggregate sample APPARATUS Steel cylinder cylindrical measure Steel temping rod Balance Compressions testing machine PROCEDURE The aggregate passing 125 mm sieve and retained on 10 mm IS sieve is selected for standard test The aggregate should be in surface dry condition before

The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate The strength of coarse aggregates is assessed by aggregates crushing test The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load

The aggregates should therefore have sufficient toughness to resist their disintegration due to impact This characteristic is measured by impact value test The aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load

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

“Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations when aggregate value 30 or higher the result may be a mistake and in such cases the “ten percent fines value” should be determined and used instead

For the crushing value test the following procedure is followed Procedure for finding the crushing value of aggregate Aggregate passing through a125mm IS sieve and retained on 10mm IS sieve is taken About 65 kg material is taken The aggregate in a surface dry condition is filled into the standard cylindrical measure in three layers approximately of equal depth Each layer is tamped 25 times with
