Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67 (Impact Value) Where, W1= Jul 16, 2014 Aggregate impact value test gives an indication of aggregate’s toughness property (i.e. property of a material to resist impact) Aggregate impact values are used to classify the stone aggregates with respect to toughness property as given below. Aggregate impact value Permissible limits of aggregate impact value report importants of aggregate crushing value report aggregate crushing value of aggregates with cement bs 812 part 110 describes a method to determine the aggregate crushing value acv which gives a relative measure of the crushing resistance of aggregate under an increasing compressive.Read more. The apparatus used for determining aggregate impact value of coarse aggregates is Impact testing machine conforming to IS: 2386 (Part IV)- 1963,IS Sieves of sizes 12.5mm, 10mm and 2.36mm, A cylindrical metal measure of 75mm dia. and 50mm depth, A tamping rod of 10mm circular cross section and 230mm length, rounded at one end and Oven. Now, the final report of aggregate impact value is calculated as, Final report of aggregate impact value test. Weight of oven dried aggregate sample (A) = 332.8 gm. Weight of fraction (dust) of aggregate passing through 2.36 mm sieve (B) = 23.2 gm. Aggregate impact value, 2.0 THEORY 2 Basically the Aggregate Impact Value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling from a set height, a prescribed number of times, onto of aggregate of a standard Construction and Building Equipment ZCRUSHER. impact value as per is code of coarse aggregate limits[2014-10-06].aggregate base course mixinng plant[2014-09-17]. aggregate impact & deval abrasion testing machineasew 185[2014-09-16]. 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.
