### definition of aggregate impact value

Jul 16, 2014· Aggregate impact value test gives an indication of aggregate’s toughness property (ie 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 (%) Toughness Properties

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 – 125mm, 10mm and 236mm, 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

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

Basically, the aggregates impact value is aggregate which provides a relative measure of the resistance of an aggregate to sudden shock or impact However, it can be explain as the aggregate crushing value which is defined as a ratio of the weight.
