The percentage mass of fines (passing a BS test sieve) formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than their crushing values.
aggregate crushing value test video. The Aggregate Impact Value Testing Apparatus, meets with BS 812, it is robustly designed to determine the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. aggregate crushing value test conclusion .

· Aggregate Impact Value Testing machine The test equipment and the test procedure are quite simple and it determines the resistance to impact of stone aggregates simulating field condition. This test can be performed even at construction site or at stone quary, as the apparatus is simple and portable.
The aggregate impact values are strong (on the average, by about 10% to 30%) than 8 the aggregate crushing values. Various agencies have specified the maximum permissible aggregate impact values for the different types of pavements, those recommended by the roads for deciding the suitability of soft aggregates in base course construction, this test has been commonly used.

emission factors for the crushing, screening, and handling and transfer operations associated with stone crushing can be found in Section, "Crushed Stone Processing." In the absence of other data, the emission factors presented in Section can be used to estimate emissions from corresponding sand and gravel processing sources.

· Aggregate Impact Value Test. AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. 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.

Tests have also shown that steel slag is an equally good substitute for gravel or crushed stone aggregate in both stabilised cement and unbound base layers. Properties of a cementstabilised mixture of slag, natural crushed stone, and % and 2% of cement (Class N) meet the compressive strength criteria set by Croatian standards [27].

The crushed aggregate sample which is finer than mm is separated and expressed as a percentage of the original weight taken in the mould. The percentage of weight passed through the IS sieve is known as Aggregate crushing value.. In situations, when the aggregate value 30 or higher the result may be a mistake and in such cases, the "ten percent fines value" should be determined ...

· 6. Impact, 10% Fines Crushing Tests If the percentage fines exceeds 30, the result may be anomalous as the broken pieces of aggregate will tend to fill the voids and prevent further crushing. In this case, the Ten Percent Fines Test is more appropriate. Some countries,, Australia and New Zealand, only use the latter test.
experiment aggregate crushing value experiment of aggregate crushing value The 'Aggregate crushing value' gives a relative measure of the resistance of Aggregates with lower crushing value indie a lower crushed fraction under Experiment No. 1—Aggregate Crushing Value Test. 3 depth
Bullas and West [4] reported the aggregate impact value did not, but the aggregate crushing value did separate suitable and unsuitable aggregate for bitumen macadam roadbase. Fookes, Gourley and Ohikere [5] recommended that combinations of physical tests such as impact, crushing and abrasion resistance be used to assess aggregate durability.
The test aims at looking for the forces required to produce 10% of fine values ( weight of fines aggregates/weight of all aggregates = 10%). This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value.
The Effect of Aggregate Properties on Concrete Concrete is a mixture of cementious material, aggregate, and water. Aggregate is commonly considered inert filler, which accounts for 60 to 80 percent of the volume and 70 to 85 percent of the weight of concrete.
