Determination of Aggregate impact Value (AIV) 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.
CONCLUSION Well shaped cubical stones provide higher resistance to impact when compared with flaky and elongated stones. From the experiment the value of AIV is 19.Chief advantage of aggregate impact test is that test equipment and the test procedure are quite simple and it determines the resistance to impact of stones simulating field condition.
Every statistical test that you report should relate directly to a hypothesis. Begin the results section by restating each hypothesis, then state whether your results supported it, then give the data and statistics that allowed you to draw this conclusion.
Procedure to determine Aggregate Impact Value i) The cup of the impact testing machine should be fixed firmly in position on the base of the machine and the whole of the test sample placed in it and compacted by 25 strokes of the tamping rod.
