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...
Jan 12, 2017· The aggregates must thus have adequate rigidity to resist their breakdown due to excessive impact This property is calculated by impact value test The aggregate impact value is a calculation of the resistance to abrupt impact, bang or shock, which may vary from its resistance to steadily, applied compressive weight Procedure:...
Experiment No 4: Determination of the aggregate impact value of different coarse aggregate sampl (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...
Feb 08, 2012· Aggregate impact and , WIResults The mean of the crushing value obtained in the two te...
The determination of crushing value of slag is as follows: The aggregate impact value should not exceed 45% by weight of the aggregate for concrete other than wearing surface The aggregate impact value should not exceed 35% by weight for concrete wearing surface such as runways, roads, pavements, floors etc [10] IS: 2386 (Part 4) The average ....
May 08, 2013· Objective For determination of the aggregate crushing value of coarse aggregate, which passes 125 mm IS sieve and retained on 10 mm IS sieve Reference Standard IS: 2386 (Part IV)-1963 Methods of test for aggregate for concrete Part IV Mechanical Properti...
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load 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...
Jun 13, 2019· Then take the, Mean = C + D / 2 Therefore, The Impact Value of Aggregate = Also Read: Test for determination of aggregate crushing value Important Notes: The aggregate crushing value should not be more than 45% for aggregate used for concrete other than wearing surfac...
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...
Jan 04, 2014· Procedure of testing Aggregate Crushing Value (ACV): 1 Make a sieve analysis and get sufficient amount of aggregate by using 140 mm passing sieve and 1000 mm retained sieve 2 After sieving fill the cylinder in thre layers by the aggregate and apply 25 blows by the tamping rod with a approximate height of 50 mm 3...
