Jul 16 2014 aggregate impact value test gives an indication of aggregates aggregate impact value test also gives an indirect indication of the strength for majority of aggregates the aggregate crushing value and aggregate impact
Chat OnlineThis test is very similar to aggregate crushing test in which a standard force 400kn is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value difference between aggregate crushing value and 10 fine by get more
Chat OnlineThe aggregate impact value testing apparatus is robustly designed to determine the aggregate impact value aiv of aggregates which provides a relative measure
Chat OnlineAggregate crushing value depends on the shape of agg also angular aggregates have a lower acv than irregular or rounded we cut a core out of the same agg say in the quarry and test for compressive strength will give a higher mpa value it can be considered as a concrete cylinder or ucs tested in lab so it is hard to corelate
Chat OnlineAggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is 2386 part iv 1963 the apparatus used is cylindrical measure and plunger compression testing machine is sieves of sizes 125mm 10mm and 236mm
Chat OnlineJul 17 2017 the aim of aggregate impact test is to determine the relative measure of the resistance of aggregate to sudden shock or impact in which in some aggregate differs from its resistance to a slowly applies compressive load the property of a material
Chat OnlineThe aggregate impact value is the measure of resistance to sudden impact of shock which may differ from its resistance to gradually applied compressive load equipments the apparatus as per is 2386 partiv 1993 consist of
Chat OnlinePdf this paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value acv and ten percent fines aggregate crushing value
Chat OnlineJul 16 2014 aggregate impact value of a sample also depends on the shape factors such as flakiness index and elongation index of the aggregates it has been found that for majority of aggregates the aggregate crushing value and aggregate impact values are numerically similar within close limits
Chat OnlineJul 17 2017 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 impact value aiv aiv is the percentage of fines produced from the aggregate sample subjecting it
Chat Onlineaggregate impact value british aggregate crushing value british microdeval abrasion frenchcanadian degradation in the shrp gyratory compactor although widely used the predictive capability of the la abrasion test was rated only fair by the researchers and project consultants
Chat OnlineAggregate crushing value acv civil engineering laboratory 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 30 the result may be anomalous
Chat OnlineWhat is the main difference between crushing test and impact test in coarse aggregate crushing test helps to determine the aggregate crushing value of coarse aggregates as per is 2386 impact test is done to determine the aggregate impact value of coarse aggregates as per is 2386 part iv 1963
Chat OnlineThe 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 aggregate used in road
Chat OnlineFeb 08 2012 aggregate impact and crushing test the test sample is subjected to 15 blows of the hammer dropping 381 mm each being delivered at an interval not less than one second5 the crushed aggregate is sieved over a 236 mm sieve the fraction passing
Chat OnlineTo evaluate the toughness of a stone ie the resistance of the aggregates to fracture under repeated impacts is called impact test is done to determine the aggregate impact value of coarse aggregate as per is 2386 partiv 1993 aggregate impact value test as per is 2386 partiv 1993
Chat OnlineFeb 08 2012 ss 1974 ss731974 specification for methods for sampling and testing of mineral aggregates sand and fillers determination of aggregate impact value aggregate crushing value and ten percent fines value singapore standard singapore2 millard rs 1993 road building in
Chat OnlineAggregate impact value test also gives an indirect indication of the strength for majority of aggregates the aggregate crushing value and aggregate impact slump compaction fator what is the relation between them
Chat OnlineImpact value of aggregate will give aggregate capability against sudden loads or forces for this test also aggregate passing through 125mm and retained on 10mm sieve is taken and oven dried fill the cylinder with aggregate in 3 layers 25 strokes of tamping for each layer
Chat OnlineExperiment 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
Chat OnlineThe 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
Chat OnlineThe aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load
