Aggregate sizes larger than 14 mm are not appropriate to the aggregate impact value test. NOTE 1 For the determination of the resistance of an aggregate to a slowly applied compressive load, see BS 812-110. NOTE 2 The titles of the publications referred to in this standard are listed in the inside back cover.
The aggregate crushing value formula is given below, Aggregate crushing value = (W3 / W) or W3 / (W2 – W1) W1 = Empty weight of cylindrical Measure. W2 = Weight of Aggregate with Cylindrical Measure. W = W2 –W1 = Weight of Aggregate Sample. W3 = Weight of crushed aggregate sample passed through 2.36 mm IS Sieve.
