  • Aggregate Impact Value Test, Procedure, Result & Standards

    Aggregate impact value is the ratio of the weight of the fraction passing through 236 mm (weight W2) by the total weight of the sample (weight W1 + W2) Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 2667 (Impact Value) Where, W1=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 Procedure o f Aggregate Impact Test The test sample consists of aggregates sized 100 mm 125Determination of Aggregate Impact Value Impact Test on01/07/2019· The ‘ Aggregate Impact Value’ is the mean of two observations, rounded to a nearest whole number Precautions Place the plunger centrally so that it falls directly on the aggregate sample and does not touch the wall of the cylinder in order toAggregate Impact value Test Apparatus, Procedure and
