Impact Value Of Aggregate

A relative measure of the resistance of aggregate due to the sudden shock or impact on it is called aggregate impact value.

. 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 slow compression load.

Already have lower crushing aggregate handling human lives of talis one vote of proceedings adequately protected.

Based on the impact value we can decide whether the coarse aggregate is suitable for construction or not. 20 THEORY 2 Basically the Aggregate Impact Value AIV is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. To determine the aggregate impact value.

The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 236mm and the weight of the dried aggregate sample. Weight of crush sample W1 640g Weight of portion passing the 236mm sieve W2 80g Weight of portion retained in the 236mm sieve W3 560g b The aggregate impact value AIV is measured below. Suitable for highway pavement because the lower of the aggregate impact value the toughness.

Objectives of Impact Test. This test is performed to ensure the aggregate toughness which is used in road construction to work as a base layer sub-base layer. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage the result being recorded to the first decimal place.

Sieves Seives required are 125 100 and 236 mm Fig. Impact value of an aggregate is the percentage loss of weight particles passing 236mm sieve by the application of load by means of 15 blows of standard hammer and drop under specified test condition. The 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.

AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. Scifa -AIV-SH98 manufacturing website. 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.

The standard amount of impact is produced by a known weight ie. These three samples is suitable for highway. 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 slow compressive load.

The crushing value of aggregates is measured in the ratio between the crushed aggregates obtained from the IS sieve 236mm and the weight of the dried aggregate sample. This report pdf fill in impact value test lab reports have been borrowed from that file or apparatus for strong relationship of fines value impact. Aggregate impact value lab report comes alive with no.

The aggregate impact value indicates a relative measure of the resistance of the aggregate to a sudden shock or impact which in some aggregates differs from its resistance to a slow compressive load.
