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.Jun 19 2016 Aggregate is a granular material such as sand gravel crushed stone crushed hydraulic cement concrete or iron blast furnace slag used with a hydraulic cementing medium to produce either concrete or mortar Coarse Aggregate Those particles that are predominantly retained on the 4 75 mm (No 4) sieve are called Coarse Aggregates.
Aggregate crushing value test determine aggregate crushing may 5 2010 coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions aggregate crushing value is a numerical index of the strength of the aggregate and it is used.Experiment No 4 Determination of the aggregate impact value of different coarse aggregate samples (BS 812) Scope significance Aggregate Impact Value The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
The average crushing value in the different tests is the actual crushing value of aggregate Important points to remember It is recommended that the crushing value of aggregate should be less than 30 If it is than 30 then 10 finer aggregate is suggested to use The aggregate whose crushing value is less than 30 can be used for.Jan 20 2020 Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture To determine the technical requirements of crushing value of coarse aggregate used in PA mixture step loading compression tests were conducted on the mixtures of PA 13 and a control asphalt mixture AC 13 respectively.
Aug 27 2019 The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample.Jan 13 2011 Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12 5mm and retained on 10mm IS Sieve are oven dried at a temperature of 100 to 110 o C for 3 to 4hrs ii) The cylinder of the apparatus is filled in 3 layers each layer tamped with 25 strokes of a tamping rod iii) The weight of aggregates is measured (Weight ‘A’) iv) The surface of the aggregates is then.
