MoreCONCLUSION. From the experiment, the value is 29.2%, 29.8%, and 29.8% are close to the maximum allowable limit for good aggregates. Hence, they can be acceptable as their Aggregate Impact value is less than 30%. Aggregate ImpactValues, (AIV's), below 10% are regarded as strong, and AIV's above 35% would normally be regarded as too weak for use ...

MoreThe 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 10.0 mm 12.5 mm. Aggregates may be dried by heating at 100-110° C for a period of 4 hours and cooled.

MoreCrush samples having an impact value of 12.5% fall in the category of 10-20%, therefore, the aggregate test sample is classified as strong and can be seen in the table below. The aggregate impact value is useful for selecting the good aggregates for road construction. Aggregate appropriate for cement wearing course should have maximum AIV of 30%.
