the apparatus of the aggregate crushing value test as per is: 2386 1963 consists of: diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in fig straight metal tamping rod may 17, 2019 concept and significance of the aggregate crushing value test. 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 material obtained when the test aggregates are subjected to a specified load study of the aggregate crushing test. this report records an investigation of the aggregate crushing test size distribution analyses were performed on various rock types, and this technique was used to investigate possible variables in the test.
advantages aggregate crushing value test report. surface dressing with aggregate chippings and bitumen, depot tray test (know the amount of binder you are spraying, and its evenness of aggregate crushing value test conclusion. aggregate impact and crushing test slideshare feb these crushing tests can reveal aggregate properties subject to per cent of the aggregate crushing value and itcan be used for the same purpose discussiona report the geological description of the aggregateaggregate crushing value test report jaw crusher ball 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 aggregate,aggregate crushing value test report.
1.the ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: aggregate crushing value 100 where weight of oven-dried sample weight in of fraction passing through 2.36 mm IS sieve. 6.video aggregate crushing value testmechanical properties of aggregates aggregate crushing value test procedure the material to be tested should pass a 14.0 mm sieve and be retained on a mm sieve. dry the sample in an oven at for four hours. place the sample in a standard cylindrical mould and tamp it. put a plunger on the top of the aggregate and place the aggregate crushing value the aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slowly applied compressive load. with aggregate of aggregate impact value higher than the result may be anomalous.
conference aggregate crushing value test report. aggregate crushing value test report discussion. aggregate crushing value test report discussion create more value to customers is the business philosophy of xuanshi machinery. We are always adhering to the quality cast technology and strength, by the quality kimono to development the road of 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 part-iv and used to verify the crushing strength of aggregates. the aggregates should be oven dried, which can passes through 12.m and retained on feb 25, 2012 the strength of coarse aggregates is assessed by aggregates crushing test. the 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. 2.0 objective.
may 08, 2013 aggregate crushing value 100 record. the mean of the two results is reported to the nearest whole number as the aggregate crushing value of the tested material. safety & precautions: use hand gloves while removing containers from oven after switching off the oven. To wear safety shoes & helmet during the time of test.aggregate impact and crushing testlinkedin slideshare aggregate impact and crushing test is recorded to the nearestwhole number as the aggregate impact value.the aiv is normally about 105 per cent of the aggregate crushing value and itcan be used for the same purpose. e.gaustralia and new zealand, only use the latter test.discussion report the geological description of the aggregateacv 100 2500 20.4 result: aggregate crushing value 20.4% result analysis: the value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality.
aggregate crushing value test lab report adnan. the value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. aggregate crushing value 45% for aggregates used for concrete for non-wearing surfaces and 25% for wearing surfaces like get pricecalculation of aggregate crushing value. the crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.m 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 100. lab reportprocedure of aggregate crushing value test put the cylinder in position on the base plate and weigh it put the sample in layers, each layer being subjected to strokes using the tamping rod. care being taken in the case of weak materials not to break the particles and weigh it
aug 11, 2020 It is recommended that the crushing value of aggregate should be less than 30%. If it is more than then 10% finer aggregate is suggested to use. the aggregate whose crushing value is less than 30% can be used for cement concrete road. the aggregate whose crushing value is less than 40% can be used for wearing surface.feb 08, 2012 two tests are required and the ten percent fines values are averaged to obtain the final result, reported to the nearest kN procedure aggregate crushing value the apparatus and sample preparation is identical with that described above for the ten percent fines test.2.
